🤠 Texas: A State the Size of a Country

What you’ll learn

1. The Size ProblemCalibrate Texas's actual scale — and understand why 'big and full' matters more than 'biggest'.El Paso is closer to San Diego (~720 mi) than to Beaumont (~830 mi), and the state spans two time zones. Texas covers ~268,000 sq mi — larger than France — but Alaska is 2.5× bigger. The real distinction is that Texas is both enormous and populous: ~31 million people, 254 counties, and a ~$2.7 trillion economy that would rank around eighth in the world.
2. The Line That Cuts Texas in HalfUse the ~30-inch rainfall line to explain why Texas is two different civilizations in one state.Near the 98th meridian, annual rainfall crosses ~30 inches — roughly the threshold for unirrigated farming. East of it: pine forest, cotton, small farms, and a southern settlement pattern. West of it: ranches, distance, and eventually true Chihuahuan desert at under 10 inches. John Wesley Powell warned Congress in 1878 that the eastern land system would break past this line; Texas shows both answers side by side.
3. How Texas Got Its PeopleUnderstand Spanish and Mexican Texas, and give an honest account of the revolution's causes.Spain held Texas for three centuries and never populated it; Mexico inherited the problem and invited Americans in via the empresario system, on terms requiring Mexican citizenship, Catholicism, and obedience to Mexican law — which abolished slavery in 1829. By 1830 Anglos outnumbered Tejanos ~10:1. The revolt was both a genuine federalist rising against Santa Anna's centralization (Zacatecas rose too) and a slaveholders' revolt — the 1836 Republic constitution made slavery legal and unrepealable.
4. 1836, and the Battle Texas LostSeparate the Alamo myth from the campaign that actually won Texas independence.The Alamo was a thirteen-day siege ending 6 March 1836 with every defender killed — a total defeat that became the founding myth, because a last stand proves character in a way a victory cannot. Goliad, where 340+ prisoners were executed after surrendering, enraged Texans more and is barely remembered. Houston retreated for six weeks trading space for time, then destroyed Santa Anna's divided, unguarded army at San Jacinto on 21 April in eighteen minutes — nine Texans dead.
5. Nine Years a Country — and the Deal That FollowedExplain the Republic years and the annexation term that still shapes Texas today.Texas was a recognized sovereign nation 1836–1845 — and broke, raided by Mexico, and losing to the Comanche. It applied to join immediately and was blocked for nine years over slavery. Because it joined by treaty as a country, it kept its public lands: Washington owns ~1.8% of Texas versus 80% of Nevada. Land set aside for a university produced Santa Rita No. 1 in 1923 and became the Permanent University Fund. Annexation allowed division into five states — never secession, as Texas v. White (1869) confirmed.
6. The Cowboy Lasted Twenty YearsUnderstand why the cattle drive existed, who actually did it, and why it lasted only twenty years.Postwar Texas had no cash and millions of feral longhorns worth ~$4 locally and ~$40 in Chicago, so ~5 million cattle were walked north 1866–1886. Roughly a quarter of trail cowboys were Black, and Mexican vaqueros invented the trade — the saddle, lasso, roundup, and the words buckaroo and lariat. Barbed wire, railroads reaching Texas, Texas-fever quarantines, and the winter of 1886–87 ended it within a decade.
7. Spindletop, and the Agency That Taught OPECExplain what Spindletop actually changed, and how a Texas railroad agency became OPEC's template.The Lucas Gusher of 10 January 1901 flowed ~100,000 barrels a day when the best U.S. wells made ~2,000 — breaking petroleum's scarcity and turning it from lamp kerosene into bulk fuel for railroads, navies, industry, and cars. The 1930 East Texas Field then crashed prices to ten cents under the rule of capture, so the Texas Railroad Commission imposed proration and effectively set the world oil price until 1972 — when Texas peaked, the limits came off, and pricing power passed to OPEC, which had copied the model.
8. The Texas TriangleUnderstand the four cities that carry the modern Texas economy, and what the no-income-tax model actually costs.The Houston–DFW–San Antonio–Austin triangle holds ~70% of Texans; Texas is more urban by share than New York state. Houston is the most ethnically diverse major U.S. city, has no zoning, and runs the largest U.S. port by tonnage plus the world's largest medical complex. DFW exists on railroads and an airport bigger than Manhattan. Texas has no income tax but among the highest property taxes, an 8%+ combined sales tax, and severance revenue — a regressive mix.
9. A Grid of Its OwnExplain ERCOT's isolation and see how one design choice produced both the renewables boom and the 2021 blackouts.ERCOT covers ~90% of Texas load and is deliberately not synchronized to the national grids — a legal strategy to stay outside the Federal Power Act. It produced the most competitive U.S. power market and the fastest buildout: Texas leads the nation in wind (~a quarter of U.S. generation), utility-scale solar, and batteries, thanks to cheap private land, fast permitting, and ~$7bn of CREZ transmission. In February 2021, unwinterized gas infrastructure froze, ERCOT came minutes from collapse, 4.5m+ customers lost power, and no neighbor could send help.
