The 22nd century, defined in the calendar of Earth as the period from 2101 to 2200, was a period of significant change, first for Earth, and then other species as well. In the early part of the century, Earth made the first steps toward a planetary government and prosperous society. The mid-century was a particularly eventful time, with the launch of Earth's first starship capable of warp 5 and man's first forays into deep space, the Xindi attack on Earth, and the Earth-Romulan War. Contacts and alliances made in the 2150s paved the way for the founding of the United Federation of Planets in 2161. (Star Trek: Enterprise)
