The southerners favored slavery but Lincoln was against it.
France was on the verge of a general election and would not act without Britain’s support. Britain felt that the Treaty of Versailles was unfair and harsh on Germany, so they decided not to tale any action. As a result of this, so did France.
Dr. Martin Luther King Jr supported non-violent protest.
For example the Albany movement where Dr. King and peaceful demonstrators were all jailed. Later on they are freed from jail. The Birmingham campaign where protests were held against businesses that only hired “White” Anglo-Saxon Americans or had segregated restrooms. These protests would include sit-ins and marches, which would get them jailed. Dr. King encouraged the nonviolent protest in order for the jails to overflow.
