3. Populorum progressio is the
encyclical written by Pope Paul
VI on the topic of "the development
of peoples" and that the economy of
the world should serve mankind
and not just the few. It was released
on March 26, 1967.

4. It touches on a variety of principles of
Catholic Social Teaching.
The progressive development of peoples is
an object of deep interest and concern
to the Church.

5. Populorum Progressio is pope Pope Paul VI’s
only social encyclical.
"Populorum Progressio" was published at a
particularly difficult moment. 1967 was
the year of the Six Day War; it was at the
height of the Vietnam War and the protest
movement against the war
"Economics Are Not to Be Separated From
Human Realities"

6. In 2009, Pope Benedict XVI published the
encylical Caritas in veritate which again
addressed many of the themes discussed
in Populorum progressio.
In 2004, the UK-based nongovernmental
development organisation Catholic Institute
for International Relations, (CIIR), changed
its name to Progressio and
establishedProgressio Ireland in Dublin. The
organisation takes its name from this
document and is based on Catholic Social
Teaching espoused in the encyclical.
