Answer:
What were the signal capitalist institutions that underpinned overseas endeavors?
The signal capitalist institutions can be found in commerce, manufacturing, and banking.
In Early Modern Europe, commerce led to the formation of companies that were becoming larger in order to finance long-distance trips. This is closely related with the development of banking, which emerged in Late Medieval Italy. The new banking institutions centralized funds from many sources, and made loans with those funds to the new commercial companies.
Finally, in manufacturing, guilds were formed and became institutions that developed better methods of production for each sector: bakery, shoemaking, woodworking, and so on.
How in turn did imperial expansion promote the further growth of capitalism?
Imperial expansion allowed European countries to obtain enormous amounts of resources from their respective colonies: silver, gold, slaves, and cash crops. The economic profit from these resources were taken back to Europe, were they could finance larger and larger companies like the British East India Company and the Dutch East India Company.
