The leaders of parliament were in favor of bringing a dutch king to the throne of england because

The Dutch king (technically, "Stadholder") was William of Orange, who was married to a member of English royal family.  William's rule in the Netherlands was one in which he did not rule absolutely as a king.  Rather, the nation there was more of a commonwealth with shared power.  That's what the English Parliament members wanted.  William and Mary, coming over from the Dutch Republic, would be willing to accept a Bill of Rights which would put restrictions on the king's power.  The move to bring William over to become King William III of England became known as "The Glorious Revolution."

The Freedmen's bureau played a huge role in the reconstruction process after the Civil War. One of the biggest things that they did was to offer essential items to families such as food, medical aid, and most importantly housing. They also offered legal aid to people who needed it the most. The Freedmen's Bureau also established numerous schools after the Civil War.
