Describe the cycle of power demonstrated from 1810 to 1830 among Spain, Mexico, Texas, and US. Who has power? (Remember: Who started with power in Texas and who ended up with power after the revolution.)

The cycle of power was from Spain to Mexico to Texas. US got hold of Texas in 1845 only.

Explanation:

From the given years here:

In 1810 Spain was in possession of the whole territory of Mexico including Texas.

After the Mexican war of independence the Mexicans were able to get the control of Texas in 1821 but that was not to be for long.

After only a few years Texas started seceding and then eventually declared itself into an independent country.

So to summarize:

1810 onward: Spain

1821 onward: Mexico

1826: Texas

US only ruled Texas from 1845 which is not a part of the given timeline.

one of the main reasons was definitely slavery. back in 1861, republican abraham lincoln was elected and ended up being a major influence in the slavery business. slavery greatly affected the texas economy because back in 1845 during the annexation of texas, slaves became a big part of the texas population. many texans that were in favor of the secession influenced groups through party ties.
