Prior to the American Revolution, there had
been a steady tide of emigration from Ireland to America, it had not assumed anything like the proportions
which this century has witnessed. At different
times during the latter half of the seventeenth century
there were causes in operation which induced extensive
emino-ration to the various Catholic countries of the
Old World, and a few ship-loads of emigrants arrived at
Barbadoes. Under the Cromwcllian government, shiploads
of Irish men, women, and children had been dispatched
to the Colonies, including New England and
to the West Indies, under conditions which left them
little better than slaves. But with the restoration of
the Stuarts there came a suspension, not only of religious
persecution, but of the Navigation Laws, which formed a
leading feature of a policy for the repression of Irish
industries theretofore enforced by England. The expulsion
of James II., and the accession of William and Mary
to the throne was accompanied by a revival of discrimination against Irish manufactures, and a flood of
emigration to all parts of Christendom followed.
