(Antioch being an exception, except for the Syriacs, in that. The Melkites and Maronites freely joined, as did the Armenians).
Isa, my brother,
I'd certainly agree that the history of conversions to Catholicism - Eastern or Latin - in most of the Slavic nations, and in many instances involving the Oriental Churches, is less than edifying (although, as we both know, neither side exhibited much Christian charity toward one another in an era when most everyone seems to have considered the sword and politico-socio-economic pressures and repression to be acceptable and necessary accompaniments to Holy Scripture - best dished up with heavy duty proselytizing and the hurling of anathemas).
I would, however, add to your list: the Italo-Grieco-Albanian Church, which owes its origin to the displacement of Albanian Orthodox to Italy due to war and their subsequent entry into union with the native Italo-Greek Catholics, in consequence of being geographically separated from their own pastoral care; the small Russian Greek-Catholic Church, formed in the aftermath of a request to be received into union by Father Nicholas (Tolstoy) in 1896 (who was, interestingly, incardinated to the Melkites on reception); the tiny Albanian Greek-Catholic Church, with its modern union dated to a 1912 request by a presbyter and his parish (and consisting now of little more than the descendent community of that initial body); the Bulgarian Greek-Catholic Church, albeit the latter's incentive for union was ecclesio-political, originating in a dispute between the Bulgarian Orthodox and Constantinople which, once resolved, resulted in the return to Orthodoxy of the vast majority of the faithful; and, the very small community of Georgian Greek-Catholics, whose Church is now only of blessed memory.
