2. And Dagmar and Sascha’s engagement one year later.
For those who don’t know why Nicholas mother was twice engaged:
Princess Dagmar of Denmark (Maria Feodorovna) was originally engaged to be married to the Grand Duke Nicolai, the eldest son of Tsar Alexander II of Russia, the Tsarevitch Nicholas. Within the family he was always called Nixa. Nixa should have succeeded his father, Tsar Alexander II. The engament took place in the summer of 1864 during the war with Prussia and Austria. Nicholas was a handsome, but delicate young man. He was well-read and the two became deeply attached. Nicholas did not have a strong constitution and contracted bronchitis. He was sent to the southern France to recuperate, but his condition deterriorated. Dagmar came from Denmark to visit her fiance but Nicholas died some days later in 1865 before he married the Danish princess.
