1791
The first Ten Amendments to the constitution are collectively known as the Bill of Rights and were proposed by Congress on September 25, 1789, and ratified by the States on December 15, 1791.
Since 1787 27 amendments have been introduced to congress. In 1791 The Bill of Rights, the 10 first amendments, was adopted. Since The Bill of Rights 17 other amendments have been adopted, which makes the total 27 amendments since 1787.
The United States Constitution has 27 Amendments as of year 2010.
After the ratification of the constitution the first congress, in 1789, proposed twelve amendments. These were sent to the states for ratification all together in September of that year. Ten of them were ratified by the states and they were formally declared to be in effect on December 15, 1791. Interestingly, the amendments had no time limits on their ratification and one of the two that were not ratified, which was actually second in the list the congress sent to the states, involving pay raises for members of congress, kicked around for a couple of hundred years and was finally ratified in 1992 as the 27th amendment.

The amendments were introduced by James Madison to the 1st United States Congress as a series of legislative articles. They were adopted by the House of Representatives on August 21, 1789,[1][2] formally proposed by joint resolution of Congress on September 25, 1789, and came into effect as Constitutional Amendments on December 15, 1791, through the process of ratification by three-fourths of the States. While twelve amendments were passed by Congress, only ten were originally passed by the states. Of the remaining two, one was adopted as the Twenty-seventh Amendment and the other technically remains pending before the states. Source http://en.wikipedia.org/wiki/United_States_Bill_of_Rights
