trade and intermarriage. One of Osman's wives was the daughter of a rich and respected sheikh of a dervish community; one of Osman's sons married the daughter of a tekvur. The chieftain of a Christian village near Osman's base was a scout and an ally in some early expeditions. It cannot be imagined that other begs of the frontiers failed to appreciate the value of such ties and to forge similar alliances. Cliental relations with wonder-working dervishes, who indeed worked wonders in capturing the hearts and minds of tribesfolk as well as of Christian or ex-Christian peasants through syncretism, were not the monopoly of the Ottomans. Nor were the Ottomans the only ones who could claim to be “raiders in the name of the faith.” Moreover, a policy of fiscal leniency (relative to late Byzantine practices), which worked well toward gaining Christian producers as subjects, was followed not only by the Ottomans but also by their rivals. They all benefited from the military potential in the restless energies and martial skills of the nomads and adventurers who had been “going West” in search of pastureland and other opportunities since around the mid thirteenth century.
Though it is difficult to assess whether the Ottomans had any comparative advantages in the use of any of these means toward expanding their sphere of control, it must at least be noted that Osman and his followers made effective use of them. Osman's political career seems to have started during the last years of the thirteenth century and to have carried him from the leadership of a community of nomadic pastoralists to the chieftainship of a beglik after he seized a few Bithynian fortresses. One particular advantage of his beglik was its location, since this base provided its forces with relatively easy access to poorly defended Byzantine territory. Successful military expeditions brought fame and riches, which were essential in attracting more warriors and dervishes as well as scholar-bureaucrats from the centers of Islamic culture. By the time of Osman's death (1323 or 1324), his small polity had the material and organizational means to strike coins, issue endowment deeds, and use siege tactics that required much more than competency in nomadic warfare. Particularly with the conquests of Bursa (1326) and Iznik (Nicaea) (1331) under Or
In taking charge of the raiding and settlement in Thrace, which eventually paved the way for conquests in southeastern Europe, the Ottomans gained a decisive advantage over other emirates, since this role brought not only immense prestige but also access to substantial material resources in the form of booty and tax revenues. But they soon faced the quintessential Ibn Khaldunian predicament of tribal war-band leadersturned-state builders: namely, the loosening of the bonds of solidarity among members of the war band as the administrative mechanisms and stately pomp of imperial polities are adopted by the leaders of the successful enterprise. In other words, as the House of Osman was being transformed into a dynasty at the head of an emerging administrative network of controls, the relatively egalitarian community of gazi commanders was giving way to a widening hierarchical space between central power and subordinate begs; not all of the latter were content with this role.

The goal of the sultanate thereafter was to enlarge its territory on the one hand and to control fissiparous dynamics on the other. Deftly making use of divisions among feudal polities, either by carrying out fierce raids or by gaining the loyalty of local populations through fiscal concessions and/or religious propaganda and of some of the local lords through incorporation, the Ottomans rapidly extended their power in the Balkans in the final decades of the fourteenth century. Of their major rivals, the Serbian kingdom was reduced to vassalage after the Battle of Kosovo (1389), and the Bulgarian one eliminated by 1394. Keeping almost a geometric sense of centralism, the Ottomans pursued a symmetrical expansion in Anatolia and reduced some of the weaker begs—first to unequal partnership, then to vassalage, and then to incorporation as removable appointees—just as they had done to many early Bithynian allies, gazi commanders, and Balkan local lords. It should be added that the forcefulness of Ottoman expansionism was also due to their extrapolitical logic in targeting important routes of commerce and sites of production.
