Some of the social similarities between classical Greece and Rome are as follows:
1. Within both Greece and Rome there was social classes. This class system was created by wealth differentiation amongst the citizens. The social classes within Greece were; slaves, freedmen, metics, citizens and women. While in Rome there were; slaves, freedmen, plebeians and patricians.
2. Both Greece and Rome practiced polytheistic religion. This means that they believed in more than one gods.

The land was cheap, so many Americans settled in Texas. Mexico tried to stop them, but they still came. Slavery was against Mexican law, but Americans brought slaves to Texas. Many American settlers and Tejanos, or Mexicans who lived in Texas, wanted to break away from Mexico. They did not like laws made by Santa Anna, Mexico’s president. The Tejanos and Texans decided to fight for independence.
Ancient societies like the Mayans had a social structure similar to Egypt's pyramid structure. Hope this helps :)
