Wawrzyniec Engeström (altern. Lars Benzelstierna von Engeström) was a 19th-century Polish aristocrat with Swedish roots, a historian, writer and political activist who made it his life's mission to build bridges between Polish and Swedish culture. The rapprochement he sought was based on anti-German and anti-Russian sentiments. In his poems A Song about Our Stars (Pieśń o gwiazdach naszych, 1874, 1883) and The Vistula: A National Fantasy (Wisła – Fantazja narodowa, 1883) he drew on Wincenty Pol's Songs of Our Land (Pieśni o ziemi naszej). They all celebrated the idea of national unity based on historical memory, religion and custom. His inspiration came from Swedish Romantic literature, whose main works he translated into Polish.
