Why did enslaved people have to educate
themselves?

No one else would, they took care of themselves.

Explanation:

Since enslaved people had to serve everyone else, they had to teach themselves because no one else would. No one cared about them, so enslaved people took it upon themselves to educate each other.

the  equal rights amendment  (era) states: "equality  of  rights  under the law shall not be denied or abridged by the united states or by any state on account of sex." congress first introduced the era in 1923, but the campaign for ratification took off in the 1960s during the  civil rightsmovement.

the main concern with the first draft of the articles of confederation was too much power in the state governments.
