A more radical solution was called for, and so, in 1226, Konrad of Mazovia took a step whose consequences for Poland and for Europe were to be incalculable. He invited the Teutonic Order of the Hospital of St Mary in Jerusalem, known as the Teutonic Knights, to establish a commandery at Chełmno and help him con—quer Prussia. The Teutonic Knights, founded at Acre in Palestine on the model of the Templars, were attracted by the idea of a mission nearer home. They thought they had found one in Hungary, where they were given the task of holding the Tatars at bay, but King Andrew II of Hungary grew wary of their ambitions and shortly expelled them.
They could see the advantages of the Polish offer, but this time the Grand Master Hermann von Salza was determined to guarantee their future. He obtained documents from the Emperor Frederick II and a bull from Pope Gregory IX authorising the order to conquer Prussia and thereafter to hold it in perpetuity as a papal fief. Before he realised what he had let himself in for, Konrad of Mazovia discovered that the lease he had granted the order on the territory of Chełmno had become a freehold.
Hermann von Salza, who still kept his sights on the Holy Land, originally saw the Prussian theatre of operations as a sideshow. He despatched a few knights there in 1229, and a further contingent took part in a crusade into Prussia in 1232-33, preached by the Dominicans, in which several Polish dukes, the margraves of Meissen and Brandenburg, the Duke of Austria and the King of Bohemia took part, along with hundreds of German knights. The order’s involvement grew when, in 1237, it took over the Sword Brothers. And it was encouraged to take a greater interest in the area by successive Popes, whose wish to see the conversion of the pagan Balts was complemented by a desire to bring as much of northern Russia as possible into the fold of the Roman Church.
This placed the order in a position to organise annual forays (reysas) against the pagans for kings, princes and knights who wished to acquit themselves of the duty to bear arms for Christ. These reysas were like safaris for the visiting grandees, who not only fulfilled their crusading vows but enjoyed a good campaign. They also took away a favourable impression of the order, which they subsequently expressed by giving it grants of land in their own countries and by supporting it diplomatically. At the same time, the increase in crusading activity in the region created tensions and problems of its own, as it was now drawing in not only Denmark, Sweden, Norway and the Polish duchies, but also the emerging state of Lithuania and the Russian principalities of Novgorod and Muscovy.
By 1283 most of Prussia had been conquered. Although it was settled by a considerable number of landless Polish and German knights, it was the Teutonic Order that ruled the province. It established a formidable stronghold at Marienburg, a number of castles throughout the territory and a port at Elbing (Elbląg) to carry trade from the province. It proved an efficient administrator, as monastic discipline precluded venality and its structure provided

a degree of continuity which dynastic states (with their disputed successions, minorities and likelihood of feckless or incompetent rulers) lacked. The knights’ rule was relatively benign to begin with. They favoured voluntary over forced conversion of the autochton—ous population, and were pragmatic enough to use local pagans to fight alongside them when necessary. But repeated revolts and apostasies made them take a more jaundiced view with time, and the autochtones were gradually all but exterminated.
In the space of fifty years, the Prussian nuisance on the Mazovian border had been replaced by a well-ordered state. This did not in itself represent a threat to the Polish duchies. But it was one of a series of developments that would.
A century earlier, in 1150, the last Slav prince of Brenna died, to be succeeded by a German. The March of Brandenburg, as it then became, encroached eastwards, driving a wedge between Slav states on the Baltic, where the outflanked Prince Bogusław of Szczecin was forced to accept German overlordship, and those to the south, like the small principality of Lubusz, which was annexed to Brandenburg outright. In 1266 Brandenburg took Santok, and in 1271 Gdańsk, thus extending its own territory to that of the Teutonic Order. The Poles retook both Gdańsk and Santok in the following year, but they would never push the German advance back to the river Oder. From the stronghold they had set up at Berlin on the river Spree in 1231, the margraves of Brandenburg looked eastward, and they would seize every opportunity to extend their dominion in that direction.
At the same time, settlers from all over Germany came in search of land and opportunity, usually well received by Polish rulers, and by the end of the thirteenth century not only Silesian and Pomeranian cities such as Wrocław and Szczecin, but even the capital, Kraków, had become predominantly German. In Silesia and Pomerania, the influx of landless knights and farmers from Germany also made itself felt in rural areas, radically affecting the will as well as the ability of local Piast rulers to stand by a disunited Poland. Like so many small shopkeepers, these minor rulers had to pay tribute to whoever was strong enough to impose protection. One by one the princes of Pomerania, outflanked by German states and undermined by the German ascendancy in their cities, particularly Hanseatic centres such as Szczecin and Stargard, had to accept the German Emperor instead of the Duke of Kraków as their overlord. This process weakened the greater Polish duchies as well, as a result of which even their independence came under threat. In 1300 King Vaclav II of Bohemia was able to invade Wielkopolska, and with the blessing of the Emperor have himself crowned King of Poland.
If the experience of the Tatar invasions had provided a powerful argument in favour of reuniting the Polish duchies into a single kingdom, this was given added weight by increasing resentment of the encroaching Germans and foreigners in general. After Bohemia’s capture of Kraków with the connivance of some of the townspeople in 1311, the Polish troops which retook it the following year rounded up all the citizens and beheaded those who could not pronounce the Polish tongue-twisters they were made to repeat.
It was also supported by the Church. Until now, this had not played a political role, merely an administrative one. Under the early Piast kings, the bishops had been little more than functionaries with no power-base of their own. The devolution of the country into separate duchies changed this, as the individual dukes needed the support of their local bishops. These were quick to perceive that if the Polish duchies were absorbed into Bohemia or Germany, the Polish Church would lose its autonomous status, and they took steps to counter the creeping Germanisation. At the Synod of Łęczyca in 1285 the Polish bishops adopted a resolution that only Poles could be appointed as teachers in church schools.
After the canonisation of Stanisław, the Bishop of Kraków put to death by Bolesław II and recognised as patron of Poland in 1253, the monk Wincenty of Kielce wrote a life of the saint in which the alleged miraculous growing together of his quartered body is described as prophetic of the way in which the divided Poland would become one again. Similarly patriotic sentiments can be detected in the chronicle of another Bishop of Kraków, Wincenty Kadłubek, written in the first years of the thirteenth century, and in the more reliable Kronika Wielkopolska, written by a churchman in Poznań in the 1280s.
