1835 Constitution of Mexico

Las Siete Leyes (Spanish: [las ˈsjete ˈleʝes], The Seven Laws) were a series of constitutional changes that fundamentally altered the organizational structure of the still-newly-independent Mexico, ending the first federal period and creating a unitary republic. Enacted under President Antonio López de Santa Anna on 15 December 1835, they were intended to centralize and strengthen the national government at a time when the country's very independence was in question. In 1846, the 1824 Constitution was restored and the second federal period began.
