I'm Positive Texas Can Become 5 States, Maybe

Once upon a time when Texas looked like this the Texicans put the whup-ass on Generalisimo Antonio Lopez de Santa Anna and Texas became its own country. The smart ones drew up a constitution but the smarter ones realized the republic was saddled with debt and wanted Texas to be part of the United States. But in 1836 the slave population numbered 5000 and the U.S. Congress said, "No way José" to statehood so Texas said, "We'll show you" and ended up with 38,753 slaves per the 1847 census. Now back up just a little to November, 1844, when James K. Polk won the presidential election on the issue of expansion. So then current President John Tyler got Congress to approve the admittance of Texas as a state. It became effective in 1845. Got all that? So anyway, both the Joint Resolution of Annexing Texas and The Ordinance of Annexation contain this language:
New States of convenient size not exceeding four in number, in addition to said State of Texas and having sufficient population, may, hereafter by the consent of said State, be formed out of the territory thereof, which shall be entitled to admission under the provisions of the Federal Constitution.
So we can!
But wait. In 1861, when the slave population in Texas was 183,000, Texas seceded from the Union due to the Great War of Northern Aggression only to be readmitted in 1865. Constitutional scholars say the secession effectively forfieted the divide-into-five-state privilege.
So we can't!
But wait. That's just what a bunch of smarty pants say. It's never been challenged in court (where the smarty pants would probably win). So we can!
It's moot. The reason originally intended was to have the possibility of increasing the number of slave states. The only reason to do so now would be to increase Texas' presence in the U.S. Senate. But barring any disaster that would make 9/11 look miniscule, Texans would never divide the state.

Back to the slavery thing. Abraham (no middle name) Lincoln signed the Emancipation Proclamation freeing the slaves in Arkansas, Texas, Louisiana (except for the parishes of St. Bernard, Plaquemines, Jefferson, St. John, St. Charles, St. James, Ascension, Assumption, Terre Bonne, Lafourche, St. Mary, St. Martin, and Orleans, including the city of New Orleans), Mississippi, Alabama, Florida, Georgia, South Carolina, North Carolina, and Virginia (except for the forty-eight counties designated as West Virginia, and also the counties of Berkeley, Accomac, Northhampton, Elizabeth City, York, Princess Ann, and Northfolk, including the cities of Norfolk and Portsmouth).
Whew. That wore me out.
The Emancipation Proclamation was signed before Al Gore invented the Internet so news was usually olds. On June 19, 1865, General Gordon Granger arrived in Galveston with 1800 federal troops and proclaimed the emancipation of the slaves. Over the years the term June 19th has contracted to Juneteenth. It's now a state holiday and is also celebrated in an increasing number of states.
