The Republic of Texas was established in 1836 after declaring independence from Mexico and lasted until 1845 when Texas joined the United States. This period marks a significant phase in Texas history where it functioned as an independent nation, complete with its own government, military, and set of laws. The years 1836 to 1845 encapsulate the entire duration of the Republic's sovereignty, during which Texas navigated its identity, formed treaties with other nations, and dealt with internal challenges and conflicts. This context emphasizes the importance of this timeline in understanding Texas' transformation from a republic to a state within the United States.
