This is the earliest Policy which accelerates the construction of Wonders. It is available quite early, and usually may be used to aid construction of all Wonders after Stonehenge. The problem is that Tier 1 governments (with the exception of Classical Republic) have only one Economic slot, so if you want to aid your Wonder construction, you'll have to either forgo all other possible Economic Policies or slot them in your government's Wildcard slot. Urban Planning, the other early Production-oriented Policy, aids general construction in all your cities; in contrast, Corvée gives you a greater Production boost for Wonders at the expense of Production that could be used for units, districts, or buildings. Think carefully about whether the investment is worth it for your civilization, gameplay style and chosen victory path, and be sure to remove Corvée as soon as you finish (or fail to finish) a Wonder.
Under Classical Republic, you can use both this Policy and Urban Planning for a substantial boost in Production without the loss of development momentum!
Civilopedia entry Edit
Although the term refers to the medieval practice of paying one’s taxes through unpaid labor – typically a certain number of days each year – “corvée” has been around since ancient Egypt. From roughly 2600 BC onward, the Old Kingdom used such “taxes” to build pyramids, temples and monuments. Imperial China had a similar system in place; Qin Shi Huang and subsequent emperors imposed it for public works such as the Great Wall and the Grand Canal. By the Middle Ages, corvée was embedded in the feudal system, with tenants required to perform construction work on the private lands of their lords. Thus, throughout history the gentry had nice homes and tombs while everyone else had hovels.
