Julius Caesar came to power in Rome, directly or indirectly, sometimes. The last one was in 49 BC, after giving Pompey, once his ally, a coup, taking him out of power and triggering the hunt for the then former president who would result in a civil war.
The articulations even undermined the forces of the Senate and Caesar had, in practice, become a dictator. This whole situation that triggered a great revolt. In a protocol, almost theatrical, meeting in the Roman Senate, dozens of senators surrounded Caesar and annihilated him with knife blows.
Hoover's response to the Great Depression was the Smoot-Hawley tariff which rose tariffs on over 20,000 products. This measure led to retaliation from foreign countries especially from Europe and they rose their own tariffs on their American imports, the American economy was hit back and it explains why Hoover's policy failed.
Hoover was nicknamed "Do nothing" by the Democrats, they blamed him for sticking to Laissez faire economics, but this accusation was wrong as he pushed for more state intervention which eventually failed.
