A few days before the sad occurrences at Damascus, the sixty thousand Jews residing at Constantinople were in the greatest peril from the following incident:--A Turk, with his little son, was in a store kept by a Jew; having occasion to leave for a few moments, he begged the Jew to take charge of the child; but being busily occupied, in attending to his customers, he forgot the boy, who ran out. The Turk returned, and asked for his son. The Jew laughed, and jokingly said, “I have killed him for the Passover." The Turk immediately fell upon him; a tumult ensued, the guard was called, and the poor Jew, under a shower of blows, was carried before the cadi. The Greeks and the Armenians, (sworn enemies to the Jews,) loudly vociferated, "throw him into the Bosphorus."
Among the Spanish Jews were many distinguished physicians, astronomers, bankers, &c.; but in 1827, Kamonho, who was quite a remarkable person, was put to death one Friday afternoon by the order of the Sultan, because he had thwarted him in the execution of a sentence of death. the corpse of this unfortunate man remained before his door all, the Sabbath day.
From that date the position of the Jews has become worse and worse; they have been persecuted by all around them, particularly by the catholic Armenians, who are under the protection of the French government. The Jews are without influence, and deprived of all protection.
It is true that they occupy the same position as the other Rajahs,--for the Turks despise all Rajahs,--but there is this essential difference:--Christian governments are interested in the Christian Rajahs; the Greek, the Armenian will ever find a protector; but to whom shall the poor Hebrew look? who will watch over his interests?As soon as you deprive one of the right of protection, you expose him to attacks from every quarter. The Jews do not suffer so much indignity from the Turks, as from the idle Europeans and the Christian Rajahs, to whose insults and mockery they are ever subject. Even in passing through the streets they are annoyed by them. The yoke they have so long been obliged to bear has destroyed their powers of resistance, and imbued their enemies with the most daring effrontery. The "hatti sheriff" promises protection to the Jew; but while the dauntless Christian will demand his rights, the shrinking Jew will suffer without pleading for relief. He has lost even the feeling that would make him conscious of his abjectness, and has not the energy to arouse himself from his sad state.The Jews of Constantinople enjoy, and a careful examination confirms the justice of their reputation, a much higher character for probity than either the Greeks or Armenians. It has become quite a proverb to place the Jews in the first rank for probity, the Armenians in the next, and the Greeks in the last. The Jews wished to enter the army, but the Greeks and Armenians would not allow them to do so. The Chacham Bashi has promised to furnish three thousand men at any time they shall be allowed to be admitted.
