History of Germany between 800 BC - 251 BC
In Europe, the Iron Age may be defined as including the last stages of the prehistoric period and the first of the proto-historic periods. The Iron Age in Europe is characterized by an elaboration of designs in weapons, implements, and utensils. These are no longer cast but hammered into shape, and decoration is elaborate curvilinear rather than simple rectilinear; the forms and character of the ornamentation of the northern European weapons resembles in some respects Roman arms, while in other respects they are peculiar and evidently representative of northern art. The dead were buried in an extended position, whereas in the preceding Bronze Age cremation had been the rule.
In Central Europe, the Iron Age is generally divided in the early Iron Age Hallstatt culture (800–450 BC) and the late Iron Age La Tène culture (beginning in 450 BC). The transition from bronze to iron in Central Europe is exemplified in the great cemetery, discovered in 1846, of Hallstatt, near Gmunden, where the forms of the implements and weapons of the later part of the Bronze Age are imitated in iron. In the Swiss or La Tène group of implements and weapons, the forms are new and the transition complete.
The Celtic culture, or rather Proto-Celtic groups, had expanded to much of Central Europe (Gauls), and, following the Gallic invasion of the Balkans in 279 BC, as far east as central Anatolia (Galatians). In Central Europe, the prehistoric Iron Age ends with the Roman conquest.
From the Hallstatt culture, the Iron Age spreads westwards with the Celtic expansion from the 6th century BC. In Poland, the Iron Age reaches the late Lusatian culture in about the 6th century, followed in some areas by the Pomeranian culture.
The ethnic ascription of many Iron Age cultures has been bitterly contested, as the roots of Germanic, Baltic and Slavic peoples were sought in this area.
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.
