The Roman Republic ended when (answer): Caesar Augustus came to power.
Diocletian created a new administrative system called the tetrarchy (rule by 4) and increased the # of provinces. He also instituted a policy that Romans had to worship the emperor and state gods and established minimum wage. Constantine stripped power from Roman senate and created extreme power for the emperor.
The role that Harriet Tubman played in during the Civil War was to work for the Union army as a nurse, cook and spy. She helped the slaves escape which was very helpful because she knew the land very well and knows which path to take when trying to avoid soldiers.
She recruited a group of former slaves to hunt for rebel camps and report on the movement of the Confederate troops.
Hope this helped :)
Have a great day
