Explanation: Due to Texas's frontier nature, business uncertainties, and the volatility of the political situation with Spain and Mexico, no newspapers survived long in Texas up to the time of the Texas revolt against Mexico. Nine publishers printed newspapers between 1819 and 1836, but only the Telegraph and Texas Register was still in publication at the time of the Texas Revolution. The Telegraph and Texas Register became the paper of record for the Republic of Texas, and played a major role in keeping citizens informed. Five years after Texas became a state in 1845, the number of newspapers had grown to thirty-six. This collection of newspapers provides critical information regarding the early history of Texas, both as a republic and a state.
