The tech tree in Civilization 6 represents one of the most intricate and rewarding systems in strategy gaming. Unlike simpler progression models, Civ 6’s technology advancement requires careful planning, resource management, and strategic foresight. Whether you’re pursuing a scientific victory, military conquest, or cultural domination, understanding how to navigate the Civilization 6 tech tree effectively separates casual players from competitive strategists. This comprehensive guide breaks down every aspect of technological progression, from early Bronze Age discoveries to late-game artificial intelligence breakthroughs.
Mastering the tech tree isn’t merely about clicking through technologies sequentially. It demands understanding which civilizations benefit from specific research paths, how to balance infrastructure development with military capabilities, and when to deviate from standard progression patterns. The game rewards players who think several eras ahead while remaining flexible enough to adapt to unexpected challenges. This guide explores proven strategies used by experienced players to optimize research timelines and achieve victory conditions faster than opponents.
Understanding the Basic Tech Tree Structure
Civilization 6’s tech tree operates on a prerequisite system where technologies unlock in logical progression. Unlike previous games in the series, Civ 6 introduced the concept of “boosts” that accelerate research when specific conditions are met. Understanding these mechanics is fundamental to optimizing your research strategy. Each technology requires a certain amount of science points to unlock, and boosts can reduce this requirement by 40%, effectively cutting research time in half.
The tech tree divides into distinct eras, each containing 4-8 technologies that must be researched before advancing to the next era. Some technologies are mandatory to progress, while others are optional but offer significant advantages. The game displays dependencies clearly, showing which technologies unlock new buildings, units, and district types. Strategic players examine the entire tree before committing to research paths, identifying which optional technologies provide the most value for their chosen victory condition.
Science generation comes from several sources: campus districts provide the primary science output, universities and research labs amplify campus effectiveness, and certain buildings like the library provide baseline science. Government policies and wonders also contribute to scientific advancement. Advanced players balance building science infrastructure with pursuing technologies that unlock additional science bonuses, creating exponential growth in research speed as the game progresses.
Ancient Era Technologies and Early Game Strategy
The Ancient Era establishes your civilization’s foundation. Your first technological choices dramatically impact mid-game success. Most players choose between three opening strategies: rushing Bronze Working for military units, prioritizing Writing for early science infrastructure, or pursuing Pottery for granaries that enable population growth. Each path offers distinct advantages depending on your civilization and starting location.
Bronze Working unlocks the Warrior unit upgrade and Bronze Age military units, essential if you face aggressive neighbors or plan early military expansion. Writing enables libraries and the Great Library wonder, accelerating science generation significantly. Pottery provides granaries that improve food storage, allowing cities to grow faster and work tiles more efficiently. Top players often recommend Writing as the optimal first technology because early science investment compounds throughout the entire game.
The Ancient Era also includes crucial early decisions like researching Code of Laws for government systems or Animal Husbandry for horse units and pastures. These choices should align with your civilization’s unique abilities. For instance, civilizations with bonuses to specific unit types benefit from rushing their prerequisite technologies. Check your civilization’s unique abilities in the Artificial Intelligence Applications guide for strategic planning insights, though Civ 6’s AI systems differ from real AI applications.
Don’t overlook the importance of achieving era stars in the Ancient Era. Earning enough era points to achieve a “Golden Age” provides significant bonuses to production and culture. This can be accomplished through various means including wonder construction, unit promotions, and technology boosts. Strategic placement of your first settlers and city development should account for future campus district locations, as districts require planning several eras in advance.
Classical Through Medieval Era Progression
The Classical Era introduces more specialized technologies and the first truly critical decisions about victory condition focus. This era marks where casual players and strategic veterans diverge significantly. Civilizations pursuing scientific victory should prioritize Mathematics and Philosophy early, as these unlock campus district adjacency bonuses and the Oracle wonder. Military-focused civilizations should research Iron Working and Horse Archery to access superior units.
Medieval Era technologies unlock crucial infrastructure including universities, which dramatically boost science output. The printing press, unlocked through Printing technology, accelerates culture generation and enables more policy swaps. Most successful players recommend researching toward Medieval Fairs and Universities as quickly as possible, as the science multiplier effect justifies the research investment. During this period, you should have established multiple cities with developing infrastructure.
The Classical and Medieval eras are where many players make critical mistakes by over-investing in military technologies without proper economic foundation. While military dominance seems attractive, civilizations without robust economic infrastructure cannot sustain prolonged conflicts. Experienced players maintain military sufficiency for defense while prioritizing economic and science technologies. This balanced approach prevents both military defeats and technological falls behind opponents.
Trade routes become increasingly important during these eras. Technologies that unlock trade routes and improve their effectiveness, like Currency and Mercenary, provide economic benefits that enable faster research. The synergy between economic development and scientific progress cannot be overstated. Your economy funds military units, science buildings, and cultural infrastructure simultaneously.

Renaissance and Industrial Era Optimization
The Renaissance Era represents the midpoint of Civilization 6 gameplay and introduces some of the most powerful technologies in the game. Printing Press, unlocked through the Printing technology, fundamentally changes how quickly you can accumulate culture and implement policy changes. The Industrial Era that follows introduces factories, which multiply production output dramatically.
Scientific players should beeline toward Scientific Theory during the Renaissance, as this unlocks museums and significantly boosts campus effectiveness. The combination of universities, museums, and campus adjacency bonuses creates exponential science growth. Industrial Era technologies like Industrialization and Steam Power unlock factories that provide production multipliers, accelerating infrastructure development and unit production.
The Renaissance also introduces crucial military upgrades through Gunpowder and related technologies. Civilizations without gunpowder units become vulnerable to opponents who possess them. However, rushing military technologies at the expense of economic development often backfires. The key is maintaining sufficient military capability while prioritizing economic and science technologies. Most competitive players research Gunpowder when it becomes available but don’t delay economic development to do so.
Coal mining becomes essential during the Industrial Era. Coal provides fuel for factories and coal plants, multiplying production output. Cities positioned near coal deposits gain significant production advantages. Strategic players plan city locations in earlier eras with future coal access in mind. The same principle applies to oil and uranium in later eras.
Modern Era and Atomic Age Advancement
The Modern Era introduces oil-based technologies that unlock powerful units and infrastructure. Oil becomes the new critical resource, similar to how coal functioned in the Industrial Era. Civilizations without oil access face significant military disadvantages. Researching technologies that improve oil extraction and refining becomes essential for maintaining military parity.
The Atomic Era introduces nuclear weapons and power plants. Nuclear weapons provide immense deterrent value, and many opponents avoid attacking civilizations with nuclear arsenals. However, nuclear weapons require uranium, which is limited on most maps. Strategic players position cities near uranium deposits in earlier eras or research technologies that improve uranium extraction efficiency.
Atomic Power technology unlocks nuclear power plants, which provide massive energy output without pollution. This enables rapid late-game infrastructure development without environmental consequences. Civilizations pursuing scientific victory should prioritize nuclear power to accelerate production of space program components. The synergy between nuclear power and space program technologies creates the fastest path to scientific victory.
During this era, you should have established clear victory condition focus. Scientific players should be constructing space program components, military players should be building nuclear arsenals or planning final military campaigns, and cultural players should be maximizing tourism output. Your tech tree research should directly support your chosen victory condition at this point.
Information Era and Late Game Technologies
The Information Era introduces the most powerful late-game technologies including the Internet and related advancements. The Internet technology provides massive science and culture bonuses, accelerating research toward final victory condition requirements. Civilizations without the Internet fall dramatically behind in science generation.
Space program technologies dominate this era for scientific victory players. Researching Launch Earth Satellite, Launch Moon Landing, and Launch Mars Colony unlocks space program projects that progress toward scientific victory. These projects require enormous production and specific resources, but completion guarantees victory. Most scientific players have already constructed launch complexes and space docks in previous eras, positioning themselves for rapid space program completion.
Diplomatic Victory becomes viable during the Information Era with technologies like Globalization. Civilizations pursuing diplomatic victory should research technologies that unlock diplomatic favor generation and world congress influence. Cultural victory players should focus on technologies that maximize tourism output and tourism multipliers.
Algorithmic technologies introduce the modern concept of artificial intelligence into the game, though these represent game-level computational concepts rather than the advanced AI applications transforming real-world industries. In Civ 6, these technologies provide late-game bonuses and unlock powerful units and buildings.
Civilization-Specific Tech Bonuses
Each civilization in Civ 6 possesses unique bonuses that affect technology research and progression. Some civilizations receive science bonuses for specific technologies, while others unlock unique technologies unavailable to other civilizations. Understanding your civilization’s unique abilities is essential for optimizing your tech tree path.
Korea, for example, receives massive science bonuses from campus districts, making them the premier scientific civilization. Their unique ability essentially reduces the cost of all technologies by increasing science output. Poland receives free social policies every era, enabling faster government evolution and policy implementation. These civilization-specific bonuses should influence your technology prioritization.
Unique technologies appear as special research options available only to specific civilizations. These technologies often provide powerful bonuses or unlock unique units and buildings. The Scythians’ Coursers unit, unlocked through a unique technology, provides exceptional early military strength. Understanding which unique technologies your civilization offers helps identify when to research them and what advantages they provide.
When playing against specific civilizations, understanding their unique bonuses helps predict their likely tech paths. If facing Korea, expect them to achieve scientific dominance unless you prioritize your own science infrastructure aggressively. Against Poland, expect them to implement powerful policy combinations that boost their civilization’s effectiveness. This knowledge allows you to counter-strategize and focus research on technologies that neutralize opponents’ advantages.

Balancing Science with Other Victory Conditions
While scientific advancement is fundamental to all victory conditions, the optimal balance between science and other priorities varies by victory condition. Scientific victory players should maximize science output at all costs, researching technologies that unlock campus districts, universities, and research labs as quickly as possible. However, even scientific players need sufficient military capability to defend against aggression.
Military victory requires significant investment in military technologies, but these civilizations still need economic and science infrastructure to sustain military production. The optimal strategy balances military unit production capabilities with economic infrastructure that generates the gold and production necessary for sustained military operations. Researching technologies that improve unit production and reduce military unit costs accelerates military victory progress.
Cultural victory requires tourism output, which scales with culture generation and tourism multipliers. Technologies that unlock museums, broadcast centers, and cultural buildings should be prioritized. However, cultural victory still requires sufficient science to research all technologies necessary for unlocking late-game cultural buildings. The balance shifts toward culture-generating technologies but maintains science infrastructure development.
Diplomatic victory depends on world congress influence and diplomatic favor accumulation. Technologies that generate diplomatic favor and unlock diplomatic buildings become priorities. However, diplomatic victory still requires sufficient military capability to prevent being invaded while pursuing diplomatic victory. The optimal diplomatic victory strategy maintains military sufficiency while researching technologies that maximize diplomatic favor generation.
Religious victory, unlocked through the Rise and Fall expansion, requires religious technologies and faith generation. This victory condition still demands balanced development across science and economic infrastructure while prioritizing religious buildings and faith generation. Most successful religious victory players maintain competitive science output while maximizing faith generation through appropriate technologies and buildings.
Common Tech Tree Mistakes to Avoid
Inexperienced players often research technologies sequentially without considering dependencies and long-term strategic implications. This approach leads to researching low-value technologies that don’t support your victory condition. Advanced players examine the entire tech tree before researching, planning 5-10 technologies ahead to ensure coherent strategy.
Over-investing in military technologies without economic foundation represents another common mistake. Military units require gold maintenance and production to build. Civilizations that research advanced military technologies without sufficient economic infrastructure cannot afford to maintain large armies. The optimal approach maintains military sufficiency while prioritizing economic development.
Ignoring civilization-specific bonuses wastes valuable advantages. If your civilization receives science bonuses for specific technologies, prioritizing those technologies amplifies your natural advantages. Similarly, civilizations with unique units should research their prerequisite technologies when available to unlock powerful units before opponents access equivalent units.
Delaying science infrastructure development creates cascading disadvantages throughout the entire game. Civilizations that don’t prioritize campus districts and universities in early eras fall behind in science generation, making it nearly impossible to catch up. Science investment in early eras compounds exponentially as additional science infrastructure multiplies research speed.
Failing to adapt to map resources and opponent strategies represents a final critical mistake. If your map contains abundant coal deposits, positioning cities near coal and researching coal-related technologies becomes essential. If facing aggressive opponents, researching sufficient military technologies to defend prevents early game defeats. Flexibility within your overall strategy allows you to respond to specific circumstances.
When considering technology investments, remember that successful tech tree navigation is similar to making smart choices about upgrade decisions in real technology systems—prioritizing foundational improvements that enable future advancement. Just as choosing appropriate computing hardware requires understanding long-term needs, planning your Civ 6 tech tree demands foresight about future requirements.
