Final answer:
The Grand Embassy was an important diplomatic and educational mission undertaken by Peter the Great to Western Europe to acquire knowledge and techniques to modernize and strengthen Russia.
Step-by-step explanation:
The Grand Embassy refers to a mission led by Peter I, also known as Peter the Great, where he visited Western Europe in disguise. This event took place from 1697 to 1698, and its primary purpose was educational for the Tsar who was eager to learn about shipbuilding, management, and governance techniques that could be applied to modernize Russia which he ambitiously sought to transform into a powerful empire. Peter's trip was critical in helping him initiate the Westernization of Russian society and government, as he brought back knowledge and ideas that eventually played significant roles in Russia's evolution into a modern state and a European power.
