Judah's reason(s) for submitting to Assyrian hegemony, at least superficially, require explanation, while at the same time indications of its read-but-disguised resistance to Assyria must be uncovered... The political and military sprawl of the Assyrian empire during the late Iron Age in the southern Levant, especially toward its outer borders, is not quite akin to the single dominating hegemony envisioned by most discussions of hegemony and subversion. In the case of Judah it should be reiterated that Judah was always a vassal state, semi-autonomous and on the periphery of the imperial system, it was never a fully-integrated provincial territory. The implications of this distinction for Judah's relationship with and experience of the Assyrian empire should not be underestimated; studies of the expression of Assyria's cultural and political powers in its provincial territories and vassal states have revealed notable differences in the degree of active involvement in different types of territories. Indeed, the mechanics of the Assyrian empire were hardly designed for direct control over all its vassals' internal activities, provided that a vassal produced the requisite tribute and did not provoke trouble among its neighbors, the level of direct involvement from Assyria remained relatively low. For the entirety of its experience of the Assyrian empire, Judah functioned as a vassal state, rather than a province under direct Assyrian rule, thereby preserving at least a certain degree of autonomy, especially in its internal affairs. Meanwhile, the general atmosphere of Pax Assyriaca in the southern Levant minimized the necessity of (and opportunities for) external conflict. That Assyrians, at least in small numbers, were present in Judah is likely - probably a qipu and his entourage who, if the recent excavators of Ramat Rahel are correct, perhaps resided just outside the capital - but there is far less evidence than is commonly assumed to suggest that these left a direct impression of Assyria on this small vassal state... The point here is that, despite the wider context of Assyria's political and economic power in the ancient Near East in general and the southern Levant in particular, Judah remained a distinguishable and semi-independent southern Levantine state, part of but not subsumed by the Assyrian empire and, indeed, benefitting from it in significant ways.
... in the Sixth Crusade, Frederick II ...concluded a treaty with the Saracens in 1229 that placed Jerusalem under Christian control but allowed Muslim and Christian alike freedom of access to the religious shrines of the city. ... Within fifteen years of Frederick's departure from the Holy Land, the Khwarisimian Turks, successors to the Seljuks, rampaged through Syria and Palestine, capturing Jerusalem in 1244. (Jerusalem would not be ruled again by Christians until the British occupied it in December 1917, during World War I.)
