Gideon v wainwright is who inspired the 6th amendment. He was charged with “breaking and entering”. Gideon didn’t have a lawyer, so he asked that they appoint one for him. The trial court denied and sentenced him to 5 years in prison. He petitioned because he felt there decision went against his constitutional rights.
