What group was taxed by the king of england before the magna carta?

 Barons,  were heavily taxed by King John to fund his wars with France, which is why they revolted and forced him to sign the Magna Carta. Peasants and farmers were not taxed because they could not contribute much to the war effort, and Parliament did not yet exist when the Magna Carta was signed
hope it works god bless

In my honest opinion , i’d say franklin d roosevelt was a president that impacted our nation , i say this because fdr is voted among top three best us presidents and he was the longest serving president by 3 terms , usually presidents only supposed to have two terms increments of 4 years , equivalent to 8 years total before election time. and he established the fdic , through the 1933 banking act and he established the us , social security system , during his presidency, and established a national minimum wage , through the fair labor standards act , fdr led the allied coalition to victory in wwii and he played a major role in the creation of the united nations.
