Mauthausen-Gusen concentration camp was the hub of a large group of German concentration camps that was built around the villages of Mauthausen and Sankt Georgen an der Gusen in Upper Austria. The camp operated from the time of the Anschluss, when Austria was annexed into the German Third Reich in early 1938, to the beginning of May 1945, at the end of the Second World War. Starting with a single camp at Mauthausen, the complex expanded over time and by the summer of 1940 Mauthausen had become one of the largest labour camp complexes in the German-controlled part of Europe, with four main subcamps at Mauthausen and nearby Gusen, and nearly 100 other subcamps located throughout Austria and southern Germany, directed from a central office at Mauthausen.
As at other Nazi concentration camps, the inmates at Mauthausen-Gusen were forced to work as slave labour, under conditions that caused many deaths. The subcamps of the Mauthausen complex included quarries, munitions factories, mines, arms factories and plants assembling Me 262 fighter aircraft. In January 1945, the camps contained roughly 85,000 inmates. The death toll remains unknown, although most sources place it between 122,766 and 320,000 for the entire complex.
The Mauthausen-Gusen camp was one of the first massive concentration camp complexes in Nazi Germany, and the last to be liberated by the Allies. The two main camps, Mauthausen and Gusen I, were labelled as 'Grade III' (Stufe III) camps, which meant that they were intended to be the toughest camps for the 'Incorrigible political enemies of the Reich'. Unlike many other concentration camps, which were intended for all categories of prisoners, Mauthausen was mostly used for extermination through labour of the intelligentsia – educated people and members of the higher social classes in countries subjugated by the Nazi regime during World War II. The main camp of the complex in Mauthausen is now a museum.
Mauthausen was declared a national memorial site in 1949. The main camp of the complex in Mauthausen is now a museum. The site remains largely intact, but much of what constituted the subcamps of Gusen I, II and III is now covered by residential areas built after the war.References:
From its origin as a small stronghold built by the ancient Illyrian tribe Dalmatae, becoming a royal castle that was the seat of many Croatian kings, to its final development as a large fortress during the Ottoman wars in Europe, Klis Fortress has guarded the frontier, being lost and re-conquered several times. Due to its location on a pass that separates the mountains Mosor and Kozjak, the fortress served as a major source of defense in Dalmatia, especially against the Ottoman advance, and has been a key crossroad between the Mediterranean belt and the Balkan rear.
Since Duke Mislav of the Duchy of Croatia made Klis Fortress the seat of his throne in the middle of the 9th century, the fortress served as the seat of many Croatia"s rulers. The reign of his successor, Duke Trpimir I, the founder of the Croatian royal House of Trpimirović, is significant for spreading Christianity in the Duchy of Croatia. He largely expanded the Klis Fortress, and in Rižinice, in the valley under the fortress, he built a church and the first Benedictine monastery in Croatia. During the reign of the first Croatian king, Tomislav, Klis and Biograd na Moru were his chief residences.
In March 1242 at Klis Fortress, Tatars who were a constituent segment of the Mongol army under the leadership of Kadan suffered a major defeat while in pursuit of the Hungarian army led by King Béla IV. After their defeat by Croatian forces, the Mongols retreated, and Béla IV rewarded many Croatian towns and nobles with 'substantial riches'. During the Late Middle Ages, the fortress was governed by Croatian nobility, amongst whom Paul I Šubić of Bribir was the most significant. During his reign, the House of Šubić controlled most of modern-day Croatia and Bosnia. Excluding the brief possession by the forces of Bosnian King, Tvrtko I, the fortress remained in Hungaro-Croatian hands for the next several hundred years, until the 16th century.
Klis Fortress is probably best known for its defense against the Ottoman invasion of Europe in the early 16th century. Croatian captain Petar Kružić led the defense of the fortress against a Turkish invasion and siege that lasted for more than two and a half decades. During this defense, as Kružić and his soldiers fought without allies against the Turks, the military faction of Uskoks was formed, which later became famous as an elite Croatian militant sect. Ultimately, the defenders were defeated and the fortress was occupied by the Ottomans in 1537. After more than a century under Ottoman rule, in 1669, Klis Fortress was besieged and seized by the Republic of Venice, thus moving the border between Christian and Muslim Europe further east and helping to contribute to the decline of the Ottoman Empire. The Venetians restored and enlarged the fortress, but it was taken by the Austrians after Napoleon extinguished the republic itself in 1797. Today, Klis Fortress contains a museum where visitors to this historic military structure can see an array of arms, armor, and traditional uniforms.
