What agreement included admitting california as a free state, eliminating the slave trade in washington,
d. c., and passing the fugitive slave act?

The agreement that included admitting California as a free state, eliminating the slave trade in Washington DC, and passing the Fugitive Slave Act was the Compromise of 1850.

Explanation:

The 1850 Compromise was created in the United States during Millard Fillmore's presidency to renew the Missouri Compromise, also called the 1820 Compromise, on slavery regulation and California's future status.

The agreement was drafted by Democrat Stephen Douglas, senator from Illinois and Whigen Henry Clay, senator from Kentucky, and was generally directed at the spread of slavery, but gave concessions to slave states, including the Fugitive Slave Act of 1850, which established certain common principles on whether escaped slaves would be returned to its owners across state borders.

The main measurements of the Compromise were:

-California was incorporated as a free state to the Union. Previously, it had been proposed to divide the state into a free state and a slave state, when it crossed the latitude proposed in the Missouri compromise.

-Texas gave up all claims to New Mexico territory while its state debt was taken over by the federal government.

-Slave trade was banned in Washington D.C. while slave owners were allowed to keep slaves in the capital (both the existence of slavery in the capital and its surface donated by two slave states, Virginia and Maryland, made the issue controversial).

-The Fugitive Slave Act required authorities in free states to return escaped slaves under certain circumstances. This part of the agreement was seen by slavery opponents as a betrayal and increased the abolitionists' resistance to the institution. Another consequence was that Canada became a main target for escaped slaves (slavery had been abolished in the British colonies in 1833). The law was declared invalid by the Wisconsin Supreme Court in 1854, and the Washington Federal Supreme Court repealed the ruling in 1859, two years before the outbreak of the Civil War.

early human migrations are the earliest migrations and expansions of archaic and modern humans across continents and are believed to have begun approximately 2 million years ago with the out of africa migration of homo erectus. this initial migration was followed by other archaic humans including h. heidelbergensis, which lived around 500,000 years ago and was the likely ancestor of both denisovans and neanderthals. early hominids were said to have "crossed land bridges that were eventually covered in water" .

within africa, homo sapiens dispersed around the time of its speciation, roughly 300,000 years ago.the "recent african origin" paradigm suggests that the anatomically modern humans outside of africa descend from a population of homo sapiens migrating from east africa roughly 70,000 years ago and spreading along the southern coast of asia and to oceania before 50,000 years ago. modern humans spread across europe about 40,000 years ago.

the migrating modern human populations are known to have interbred with local varieties of archaic humans, so that contemporary human populations are descended in small part (below 10% contribution) from regional varieties of archaic humans.

after the last glacial maximum, north eurasian populations migrated to the americas about 20,000 years ago. northern eurasia was peopled after 12,000 years ago, in the beginning holocene. arctic canada and greenland were reached by the paleo-eskimo expansion around 4,000 years ago. finally, polynesia was peopled after 2,000 years ago, by the austronesian expansion.
