Wacław Aleksander Maciejowski (10 September 1792[1] – February 10, 1883)[2] was a Polish historian.
Maciejowski was born in Těrlicko near Cieszyn.[1] He studied in Warsaw, Berlin, and Göttingen, and became professor of law at the University of Warsaw in 1819.[2]
He wrote three major works: a history of Slavic legislation (1832–38, 4 vols.; 2nd ed. 1856–65, 6 vols.), a history of Polish literature since the 16th century (1851–62, 3 vols.) and a history of the peasants of Poland (1874);[2] the latter was the first monograph to be written on the Polish peasantry.[3] He followed the historical Romanticism of Joachim Lelewel,[3] and had a Pan-Slavic outlook.[2]
