Task: Question Answering
Input (English): Passage: The Convention of 1833 (April 1–13, 1833), a political gathering of settlers in Mexican Texas, was a successor to the Convention of 1832, whose requests had not been addressed by the Mexican government. Despite the political uncertainty resulting from a recently concluded civil war, 56 delegates met in San Felipe de Austin to draft a series of petitions to the Government of Mexico.
The volatile William H. Wharton presided over the meeting.  Although the convention's agenda largely mirrored that of the Convention of 1832, delegates also agreed to pursue independent statehood for the province, which was at the time part of the state of Coahuila y Tejas. Under the guidance of Sam Houston, former governor of the US state of Tennessee, a committee drafted a state constitution to submit to the Mexican Congress. The proposed constitution was largely patterned on US political principles, yet retained several Spanish customs.  Delegates also requested customs exemptions and asked that a ban on immigration into Texas be lifted.
Some residents complained that this convention, like its predecessor, was illegal.  Nevertheless, Stephen F. Austin journeyed to Mexico City to present the petitions to the government. Frustrated with the lack of progress, in October Austin wrote a letter encouraging Texans to form their own state government.  This letter was forwarded to the Mexican government and Austin was imprisoned in early 1834.  During his imprisonment, the federal and state legislatures later passed a series of measures to placate the colonists, including the introduction of trial by jury.  Austin acknowledged that "[e]very evil complained of has been remedied.". 
Question: Where were the petitions created that the man who traveled to Mexico City presented?
Output (English): The Convention of 1833.
