The Church initially ignored Martin Luther, but Luther's ideas (and variations of them, including Calvinism) quickly spread throughout Europe. He was asked to recant (to disavow) his writings at the Diet of Worms (an unfortunate name for a council held by the Holy Roman Emperor in the German city of Worms). When Luther refused, he was excommunicated (in other words, expelled from the church). The Church's response to the threat from Luther and others during this period is called the Counter-Reformation ("counter" meaning against).
Studies have demonstrated that roundabouts are more secure than a conventional stop sign or flag controlled convergences. Roundabouts lessened damage crashes by 75 percent at crossing points where stop signs or flags were beforehand utilized for activity control, as per an investigation by the Insurance Institute for Highway Safety.
