Modern Catalanism draws on three different traditions: federal republican Catalanism, led by Valentí Almirall, the editor of Diari Català and the author of Lo catalanisme; cultural Catalanism, which drew intellectuals around the magazine La Renaixensa; and Catholic, traditionalist Catalanism, whose supporters included ideologists such as the bishop Josep Torras i Bages, and which published La Veu de Montserrat. The first Catalanist Congress was held in 1880 and two years later, the Catalan Centre was founded. The presentation of a petition of injustices, known as the Memorial de Greuges, to Alfonso XII in 1885 attracted the industrial bourgeoisie to Catalanism. In 1891, the Catalanist Union was formed.
