When Emperor of Mexico Agustín de Iturbide abdicated in March 1823, the law was annulled once again. In April 1823, Austin induced the congress to grant him a contract to bring 300 families into Texas. He wanted honest, hard-working people who would make the colony a success. In 1824, the congress passed a new immigration law that allowed the individual states of Mexico to administer public lands and open them to settlement under certain conditions. In March 1825, the legislature of the Mexican state of Coahuila y Tejas passed a law similar to the one authorized by Iturbide. The law continued the system of "empresarios", as well as granting each married man a league of land, , with the stipulation that he must pay the state $30 within six years.
