Confederates
Ancestry: Most White Confederates or Euro-Confederates tend to be British descendants (i.e. English, Welsh, Scottish and Ulster-Scots) but some have Irish, German, French/Cajun, Italian, Greek, Polish, Spanish, Jewish (Ashkenazic and Sephardi) and/or Serbian descendants as well. Black Confederates or Afro-Confederates are descended from slaves taken from West Africa. Creole Confederates have mixed ancestry (European, African and/or Amerindian). Indian Confederates are descended from the Five Civilized Tribes (Cherokee, Chickasaw, Chochtaw, Creek/Muscogee and Seminole). Asian Confederates are mostly Filipino and Chinese.
Location: Confederate States of America (CSA) with some diaspora in Britain, France and a few other countries.
Religion: Protestant Christianity; Some practice Roman Catholic Christianity, Orthodox Christianity, Judaism and occasionally old Indian faiths. A small minority are atheists.
Population: 106 million (75%-80% White, 5%-15% Black, 2.1%-3.1% Creole, 1.5% Indian and 0.5% Asian)
Culture: Confederate culture is based primarily around the planters and Africans from the antebellum era.
Language: Confederate English (Basically British English with a Southern twang)
History: The Confederates owe their existence to the planter dominated society of antebellum America from the 18th century and 19th century respectively. The increasing divide between the South and the North both culturally and ideologically led to tensions boiling every now and then but largely remaining peaceful later on. However by the early to mid 1850s, intersectional tension had reached it's boiling point after the Battle of Santa Fe between the United States and Texas this of course led to the creation of the Confederate States in 1853. The Confederate States fought and won the War of Confederate Independence/War of the Southern Rebellion between 1853-1855. Since then, the Confederate States have continued to develop their culture which underwent a number of changes such as the reluctant abolition of slavery in 1877 due to the Panic of 1873, the Negro Exodus*, the Cuba War, the Banana Wars, World War I, World War II, the Cold War and the present day.
Notes:
1. Because the Confederate States won the War of Confederate Independence/War of the Southern Rebellion (the Civil War's name ITTL), there is no equivalent of sharecropping since Reconstruction never happens. Also, since slavery in the Confederate States ended due to the Panic of 1873 without war the race relations between Whites and Blacks while are not nearly as bad as OTL but still not on equal terms and with the slaves freed many are reluctant to accept them owing to competition with poor whites and fears of miscegenation this led to most emigrating to the United States in what became known as the Negro Exodus or sticking to peonage for the whites that are willing to employ them.
