The settlement of Texas progress well for some time under the Mexican constitution of 1824, but by 1830 the relations between Texas and the central government began to go bad. The central government ordered the end to emigration of citizens of the United States into Texas. This clumsy attempt to retain the Spanish character of the region, did for some time repress the influx of settlers from the East and North, but greatly antagonized those already in Texas who had maintained contacts with their families in the United States. Then on the 26th of June 1832, Domingo de Ugartechea, the commander stationed at Anahuac, order his troops to seize a field gun in the possession of the local community of Velasco. The towns peoples refusal to relinquish the gun resulted in a sustained exchange of small arms fire which went on for several days, with more the a dozen killed on each side. the exchange ended when the Mexican troops had used up the last of their ammunition in the exchange. The troops withdrew leaving the gun in the hands of the towns people. Although Domingo de Ugartechea is relieved of duty due to his over reaction, this event greatly inflamed many across the region. In response to the rising outrage The Adelsverein begins to open its meeting to other Texans, starting on the first of October 1832 representatives from across Texas met in the town of San Felipe on the Brazos River. The attendees elect Friedrich Ernst as convention president and formulate plans to resisted the oppression of the central government. A second convention was held on 2 October 1833 and a petition for the Mexican government. This was delivered in person by Friedrich Ernst. The central government promptly arrested him, and held him in custody for nearly a year.		Shortly after the release of Friedrich Ernst, The Adelsverein organizes a third convention in the summer of 1835 in the almost openly rebellious town of Ernst. When Santa Anna revoked the Constitution of 1824 and declared himself dictator in 1835, the German nobles feared that the autonomy of action they had enjoyed under the 1824 Mexican Republic constitution would be lost. To those from the United State who had fled the Panic of 1819 and flocked to Mexican Texas were apprehensive about the prospect of living under a dictatorship, and the Tejanos as well had grown accustom to local control and the smooth working of the German lead local and state government and its on going good relations with the Comanche leadership. Seeing no particular external threat, none of the population Texas saw the real need for the protection of a Mexican dictator. The population of the region at the time of the convention is estimated as: 30,000 Germans, 21,000 Non-German Whites, 14,200 Indians, 3,500 Tejanos, and 5,000 Blacks (both free and slave). With a puerility and a record of good relations with each of the other member groups of the region, the Germans were the natural leaders of the convention. With the secret financial backing the organization powers of the Adelsverein, the pro-aristocratic could have passed an authoritarian form of government, but to assure the maximum cooperation within the community a liberal democratic constitution was drawn up and submitted to the convention. The constitution included provisions for emergency powers to be vested in the executive in times of threat. Also included was special recognition of the Comanche allowing them extended self-rile powers, and provision for the continuation of slavery and full rights for freed blacks. These provision were to assure the favorable response of slave owning former Americans and those free Blacks who were in the nation. The status of the children of slaves was not laid out in detail, which would be used latter to bring an end to the practice in one lifetime.
