Mackiewicz joined the Polish Military Organisation in 1917 and served as a volunteer in the Polish Army during the Polish-Soviet War of 1919–21. He published and the editor-in-chief of the independent Wilno (Vilnius) periodical titled "Słowo," wholly financially supported by the noble families of the former Grand Duchy of Lithuania. He actively promoted the idea of the so-called Jagellonian Poland, i.e., return to the Polish-Lithuanian Commonwealth style of governance in Eastern Europe.
He supported Józef Piłsudski and in 1928–35 served as a deputy to the Sejm (Poland's parliament), representing the Piłsudskiite Nonpartisan Bloc for Cooperation with the Government.
After Piłsudski's death in 1935, Mackiewicz criticized the ruling elite and in 1939 was imprisoned for 17 days at the Bereza Kartuska detention camp.
On 18 September 1939, a day after the Soviet attack on eastern Poland during the Soviet-German Invasion of Poland, he left Poland.
Upon the Allies' betrayal of Poland at the Yalta Conference, and subsequent occupation by Stalin of Poland and later establishment of the Communist Poland, Mackiewicz, as so many political exiles remained abroad and was politically active in the Polish émigré community. He served as prime minister of the Polish government-in-exile in 1954–55 .
In 1956 Mackiewicz returned to Poland.
He was the older brother of ardent enemy of the communist system, writer Józef Mackiewicz.
