What were three ways abolitionists sought to achieve their goals?

The abolitionists movement made an effort to end slavery in a nation filled with personal freedom. The abolitionists themselves over time grew more strident in their demands and put in place all manner of stratergies to persuade the leadership of the USA and the American public to end slaverly. 
The first strategy they employed was to unite groups of like-minded people to fight as one. Another on of the strategies most famous of all was the Underground Railroad. This was a network of assistance for runaway slaves. The famous Levi coffin and his wife Catherine helped very many slaves on the underground rail. As a result, Coffins home due to his prominence was named the Grand Central Station.

Activists, also, helped the abolitionists spread their message through the press. Several newspaper like The liberator circulated strong attacks on government sanctioned bondage. Publications like poems, leaflets, essays, sermons and songs contained anti-slavery poems.

Other abolitionists felt that extreme violence was the only option to end slavery. They formed militants who resorted to deadly tactics and exercised executions of perpetrators.
