Question

what was the first step that hitler took after being the chanceler of Germany

Answer 1

After he became Chancellor in January 1933, Hitler transformed his democratic position into dictatorial power.   Calling an election - and taking advantage of the Reichstag fire - he got the Reichstag to pass the Enabling Act.   Then, using the power this gave him to make his own laws, he set up the Gestapo, banned Trade Unions and opposition parties and (on the Night of the Long Knives, July 1934) removed even the opposition within the Nazi Party.   

       When Hindenburg died, Hitler declared himself Fuhrer
