Question: When was Herbert Blöcker's native province captured by Prussia and the Austrian Empire?

The Province of Schleswig-Holstein (German: "Provinz Schleswig-Holstein" , ] ) was a province of the Kingdom of Prussia and the Free State of Prussia from 1868 to 1946.  It was created from the Duchies of Schleswig and Holstein, which had been conquered by Prussia and the Austrian Empire from Denmark in the Second War of Schleswig in 1864.  Following the Austro-Prussian War in 1866, which ended in Austrian defeat, Schleswig and Holstein were annexed by Prussia.  The province was created in 1868 and also included the Duchy of Lauenburg since 1876. <SEP> Austrian literature is the literature written in Austria, which is mostly, but not exclusively, written in the German language.  Some scholars speak about Austrian literature in a strict sense from the year 1806 on when Francis II disbanded the Holy Roman Empire and established the Austrian Empire.  A more liberal definition incorporates all the literary works written on the territory of today's and historical Austria, especially when it comes to authors who wrote in German.  Thus, the seven volume history of Austrian literature by the editors Herbert Zeman and Fritz Peter Knapp is titled "History of the Literature in Austria".  The Austrian literature must be considered in close connection with German literature in general, and the borderline between proper German literature and the Austrian one is porous, due to rich and complex cultural exchanges. <SEP> Herbert Blöcker (January 1, 1943 – February 15, 2014) was a German equestrian and 3-time Olympic medalist.  He won a silver medal at the Olympics in Fontainebleau in 1980 following by winning another silver in eventing at the 1992 Summer Olympics in Barcelona.  He was born in Schleswig-Holstein.  During the same Olympic event he won a bronze medal too and then participated in the 1996 Summer Olympics in Atlanta, Georgia.  In 2008, both he and his Olympic horse, "Feine Dame", were inducted into the International Association of Eventing Hall of Fame.  Blöcker died of cancer on February 15, 2014 at the age of 71 in Elmshorn. <SEP> The Province of West Prussia (German: "Provinz Westpreußen" ; Kashubian: "Zôpadné Prësë" ; Polish: "Prusy Zachodnie" ) was a province of the Kingdom of Prussia from 1773 to 1824 and again from 1878 (with the Kingdom itself being part of the German Empire from 1871); it also briefly formed part of the Weimar Republic's Free State of Prussia until 1919/20.  It was created out of the earlier Polish province of Royal Prussia following the First Partition of Poland.  In February 1920, following Germany's defeat in 1918, West Prussia was divided: the mainly Slavic-speaking central parts became the Pomeranian Voivodeship of the Second Polish Republic, also known as the Polish Corridor; the city of Danzig became the Free City of Danzig, a semi-autonomous city-state under the protection of the League of Nations; the remaining territory was retained by the Free State of Prussia/Weimar Republic, with the western parts being joined to what remained of the former Province of Posen to form the new Posen-West Prussia Province, and the eastern parts being joined to the Province of East Prussia as Regierungsbezirk West Prussia.  The territory was included within Reichsgau Danzig-West Prussia 1939–45, after which it became part of Poland.
