Tsar Alexander I (1777 –  1825), also known as Alexander the Blessed, served as Emperor of Russia from 23 March 1801 to 1 December 1825, and Ruler of Poland from 1815 to 1825, as well as the first Russian Grand Duke of Finland and Lithuania.

Alexander knew Napoleon Bonaparte, Francis I of Austria, Klemens Wenzel Prince von Metternich, Johann Josef Wenzel Graf Radetzky von Radetz.

According to Russian homeopathic physician Carl Bojanus, Homeopathy entered Russia in the last years of Emperor Alexander I’s rule. In 1824, Karl Jakob Adam who, the previous year, had become acquainted with Samuel Hahnemann, arrived in Russia from Germany. He introduced to homeopathy Dr. O F Schering, who later became the Chief physician of the Imperial Guardian Board.

Alexander’s nephew, Alexander II, was a patient of German botanist and homeopathic physician Carl Bernhard von Trinius who had settled in Russia during the reign of Alexander I.
