World leaders arrived at the United Nations on Tuesday (September 23) for the annual General Assembly which begins its 80th session. The 193-member world body hosts six days of speeches by nearly 150 heads of state or government along with dozens more ministers.

The United Nations was formed in 1945 with 51 original members and has since grown to 193 members. Leaders of two non-member observer states - known at the U.N. as the Holy See and the State of Palestine - and an observer member, the European Union, can also speak.

It is tradition for Brazil to always be the first member state to speak. This is because in the early years of the world body Brazil stepped up to speak first when other countries were reluctant to do so, say U.N. officials.

As host to the U.N. headquarters in New York, the United States is the second country to address the General Assembly.

From there the list is then based on hierarchy and generally a first come, first served basis. Heads of state speak first, followed by deputy heads of state and crown princes, heads of government, ministers and lower-ranking heads of a delegation.
