Question

in the compromise of 1850, what concessions or benefits were given to appease pro - slavery states?

Explanation:

The Compromise of 1850 included several provisions to appease pro - slavery states. One key element was the Fugitive Slave Act. This act required that escaped slaves be returned to their owners, even if they had reached free states. It placed a legal obligation on citizens of free states to assist in the capture and return of fugitive slaves. Another aspect was that the new territories (such as Utah and New Mexico) would decide on the issue of slavery through popular sovereignty. However, in practice, this could be influenced by pro - slavery settlers moving into the areas. Also, the slave trade (but not slavery itself) was abolished in Washington D.C., which was a small concession to the anti - slavery side but still left the institution of slavery intact in the nation's capital.

Answer:

The Fugitive Slave Act (which required return of escaped slaves), popular sovereignty in new territories (which could be manipulated by pro - slavery forces), and the fact that slavery itself remained in Washington D.C. (with only the slave trade abolished) were concessions to pro - slavery states.
