Mieczysław Pieriejasławski-Jałowiecki was a Polish diplomat, agronomist, writer and nobleman. Mieczysław was born in his family manor in Saldutiškis on the lands of the partitionedPolish–Lithuanian Commonwealth, or in Rostov-on-Don. His mother, Anela, was a sister of Stanisław Witkiewicz; she was also a distant relative of the Piłsudski family. His father, general Bolesław, was an engineer, the grandson of a Russian Army general who sided with the Polish 1830–31 insurgents during the November Uprising and was sentenced to death, but pardoned. He graduated from the Riga Technical University, studying agronomics and chemistry, finishing agronomics studies. He also served in the Russian army, and continued studies at the University of Bonn. Before World War I he worked for the Russian government as the agricultural consul in Germany, was a director or a board members of several organizations and presided over the sejmik of local nobility. He worked at the Vilnius Land Bank. His agricultural possessions were seen as model by many in Lithuania, he was frequently visited by other land owners interested in his methods; he also gave talks and presentations on the agronomic subjects. During World War I he served in the civilian arm of the Russian Army, reaching the rank of colonel. After the war he found that his estates had been taken over by the German administration, whose representatives refused to turn them over to him. At the same time, he was worried by the worsening relations between Poles and Lithuanians. He was a vocal representative of the many among the localPolish nobility who wanted to reach a compromise solution with the Lithuanians ; he was involved in direct negotiations with the Lithuanian president Antanas Smetona. Machaliński, in his biographical sketch of Jałowiecki, writes that he was "shocked by the growing hostility of Lithuanians towards the Poles". Jałowiecki himself, after the failure of his attempt to reach a compromise with the Lithuanian authorities, wrote: "For me and many of my compatriotes... who were raised in the spirit of love for Lithuania, Lithuanian people... this new direction was totally incomprehensible." As the tensions between Poles and Lithuanians grew, he became involved in the organization of self-defense forces, and was one of the members of the delegation from the Vilnius region to Józef Piłsudski in Warsaw, requesting his aid. In Warsaw, he began working for the government of Second Polish Republic, employed as a diplomat for the Polish Ministry of Foreign Affairs; he was the Polish government's delegate to Gdańsk in the years 1919–1920. In Gdańsk he was involved with Herbert Hoover's American Relief Administration. Afterwards, unable to return to his Lithuanian homeland, he bought a new estate in Kamień, near Kalisz. The Saldutiškis, looted during the war, was converted by the Lithuanian state into administrative offices and a primary school while the former barn was converted into a parish church. After German invasion of Poland he left for the United Kingdom, where he was a politician and social activist in the Polish government in exile. He stayed in the UKafter the war. Till his death he was involved in the activities of the British Polonia, publishing books and brochures about agronomics and about his homeland. In 1962 he died near London. Mieczysław was also a writer, and has published several books in the Polish language about his diplomatic career and on agronomic subjects. He also wrote a diary trilogy, describing his life in Na skraju imperium, Wolne Miasto and Requiem dla ziemiaństwa.
