The Legaran Conference was the first meeting between the United Federation of Planets, represented by Ambassador Sarek, and the Legaran delegation in 2366 in which first contact took place and a treaty was established between the two organizations. It was held aboard the USS Enterprise-D in orbit of Legara IV.
The Federation considered many benefits in conducting relations with the Legarans for a long time. The conference was the culmination of 93 years of preliminaries by Ambassador Sarek, in major part due to the protocol the Legarans required. In fact, three months were spent simply to establish an agenda.
