his brother Ferdinand;
and has ever since been dwindling to the weak condition in which it now
is. This is a most interesting part of the history of Europe, of which it
is absolutely necessary that you should be exactly and minutely informed.

There are in the history of most countries, certain very remarkable eras,
which deserve more particular inquiry and attention than the common run
of history. Such is the revolt of the Seventeen Provinces, in the reign
of Philip the Second of Spain, which ended in forming the present
republic of the Seven United Provinces, whose independency was first
allowed by Spain at the treaty of Munster. Such was the extraordinary
revolution of Portugal, in the year 1640, in favor of the present House
of Braganza. Such is the famous revolution of Sweden, when Christian the
Second of Denmark, who was also king of Sweden, was driven out by
Gustavus Vasa. And such also is that memorable era in Denmark, of 1660;
when the states of that kingdom made a voluntary surrender of all their
rights and liberties to the Crown, and changed that free state into the
most absolute monarchy now in Europe. The Acta Regis, upon that occasion,
are worth your perusing. These remarkable periods of modern history
deserve your particular attention, and most of them have been treated
singly by good historians, which are worth your reading. The revolutions
of Sweden, and of Portugal, are most admirably well written by L'Abbe de
Vertot; they are short, and will not take twelve hours' reading. There is
another book which very well deserves your looking into, but not worth
your buying at present, because it is not portable; if you can borrow or
hire it, you should; and that is, 'L' Histoire des Traits de Paix, in two
volumes, folio, which make part of the 'Corps Diplomatique'. You will
there find a short and clear history, and the substance of every treaty
made in Europe, during the last century, from the treaty of Vervins.
Three parts in four of this book are not worth your reading, as they
relate to treaties of very little importance; but if you select the most
considerable ones, read them with attention, and take some notes, it will
be of great use to you. Attend chiefly to those in which the great powers
of Europe are the parties; such as the treaty of the Pyrenees, between
France and Spain; the treaties of Nimeguen and Ryswick; but, above all,
the treaty of Munster should be most circumstantially and minutely known
to
