The Federalist Era was a period in American history from roughly 1789-1801 when the Federalist Party was dominant in American politics. This period saw the adoption of the United States Constitution and the expansion of the federal government. In addition, the era saw the growth of a strong nationalistic government under the control of the Federalist Party. Among the most important events of this period were the foreign entanglements between France and Great Britain, the assertion of a strong centralized federal government, and the creation of political parties. The First Party System of the United States featured the Federalist Party and the Democratic- Republican Party (also known as the Anti-Federalist Party).
