Krakus Mound, an 8th-century burial mound in Kraków
The main event that took place within the lands of Poland in the Early Middle Ages was the arrival and permanent settlement of the Slavic peoples. The Slavic migrations in the area of contemporary Poland started in the second half of the 5th century CE, some half century after these territories were vacated by Germanic tribes, their previous inhabitants. The Slavs lived from cultivation of crops, but also engaged in hunting and gathering. They formed small tribal organizations, some of which coalesced later into larger, state-like ones. Beginning in the 7th century, these tribal units built fortified structures with earth and wood walls and embankments, called gords. By the 9th century, the Slavs had settled the Baltic coast in Pomerania, which subsequently developed into a commercial and military power trading with the Old Prussians and the Vikings. During the same time, the tribe of the Vistulans, based in Kraków and the surrounding region, controlled a large area in the south. But it was the Polans who turned out to be of decisive historic importance. They went through a period of accelerated building of fortified settlements and territorial expansion beginning in the first half of the 10th century. Under Mieszko I, the expanded Polan territory was converted to Latin Christianity in 966, which is commonly regarded the birth of the Polish state. (Full article...)
King Vladislaus IV as painted by Peter Paul Rubens
Vladislaus IV (Władysław IV Waza; 1595−1648) was a Polish–Swedish prince of the House of Vasa. He reigned as king of Poland and grand duke of Lithuania from 1632, and also claimed the titles of king of Sweden and grand duke of Muscovy (Russia). He was the son of King Sigismund III of Poland and Sweden, and his wife, Queen Anna of Habsburg. The teen-aged Vladislaus was elected tsar by the Seven Boyars in 1610, but did not assume the Russian throne because of his father's opposition and a popular uprising in Russia. Following his father's death in 1632, he was elected king of Poland, with no serious contenders. Vladislaus was fairly successful in defending the Polish–Lithuanian Commonwealth against invasion, notably through his personal participation in the Smolensk War. He supported religious toleration, carried out military reforms, and was a renowned patron of the arts. The king failed, however, to realize his dreams of regaining the Swedish crown, conquering the Ottoman Empire, strengthening royal power, and reforming Polish internal politics. He died without a legitimate male heir and was succeeded by his half-brother, John Casimir. Vladislaus's death marked the end of relative stability in Poland. (Full article...)
Statue of Duke Leszek the White in the village of Marcinkowo. Leszek was a duke of Kraków and, formally, sovereign of all Poland. In 1227 in Gąsawa, he convened with other Polish dukes, including Vladislaus Spindleshanks of Greater Poland, Henry the Bearded of Lower Silesia and Conrad of Masovia. Participants of the summit were attacked, probably on the orders of Duke Swantopolk II of Pomerania, in the morning of 24 November 1227. Leszek, who was then having a bath, attempted to escape, naked, on horseback, but he was captured and killed by the assassins in a nearby forest.
