On May 8, 1828, Swiss businessman and social activist Henry Dunant was born. He is best known for the creation of the International Committee of the Red Cross in 1863. Also the 1864 Geneva Convention was based on Dunant's ideas. In 1901 he received the first Nobel Peace Prize together with Frédéric Passy.
On March 4, 1394, Infante Henry, Duke of Viseu, better known as Henry the Navigator, was born. He was an important figure in the early days of the Portuguese Empire and the Age of Discoveries in total. He was responsible for the early development of European exploration and maritime trade with other continents.
On January 25, 1077, Holy Roman Emperor Henry IV arrived at the gates of the fortress at Canossa in Emilia Romagna beyond the Alpes to declare atonement and to pledge for forgiveness from Pope Gregory VII, who had excommunicated Henry earlier from church. Henry's act of penance became known as the “Walk to Canossa” (German: Gang nach Canossa). It took wisdom, patience, and self-restraint. It was also a brilliant strategy because he basically forced the Pope to forgive him.
On December 29, 1170 AD, Thomas Becket, Archbishop of Canterbury, who engaged in conflict with Henry II of England over the rights and privileges of the Church, was assassinated by followers of the King in Canterbury Cathedral. The very last hours of Thomas Becket’s life are the reason why we remember him at all. If the four knights sent for his assassination had not completed their bloody work as he defied their master King Henry II to the last, Becket might have been only slightly better known than his predecessor Theobald.
