When we started looking for President Obama's campaign promises, we knew we might not find all of them, and we hoped our readers would alert us to promises we had missed. Today we are adding our first promise based on reader feedback: Obama's pledge to recognize the Armenian genocide.

The issue has been a hot-button issue on the world stage because the government of Turkey has objected to the use of the term "genocide" as inaccurate and inflammatory.

A 2007 resolution in the U.S. House of Representatives said the Armenian genocide was carried out by the Ottoman Empire between 1915 and 1923, and resulted in the deaths of 1.5 million. The resolution failed in the face of Bush administration concerns that it would alienate Turkey, which borders Iraq.

So we add this promise to our database as promise No. 511.
