What was the purpose of the Organic Act signed by Abraham Lincoln?

The purpose of the Organic Act signed by Abraham Lincoln was to separate Arizona territory from New Mexico territory, which is why this answer is accurate. The Organic Act of 1862 aimed to organize the territories acquired in the Mexican-American War and to address the governance of newly created areas. By designating Arizona as a separate territory, the act established a distinct legislative framework, allowing for local governance and increased attention to the unique needs of the region.

While the other choices touch on important historical contexts, they do not specifically relate to the key function of the Organic Act. The act did not primarily focus on providing funding for statehood or facilitating the annexation of Texas, as those concerns were addressed through separate legislative measures. Additionally, the establishment of a new governing body in Arizona is a direct outcome of the act, but it is the separation from New Mexico that defines its purpose and importance.
