Reborn Poland faced a host of daunting challenges: extensive war damage, a ravaged economy, a population one-third composed of wary national minorities, and a need to reintegrate the three zones kept forcibly apart during the era of partition. Under these trying conditions, the experiment with democracy faltered. Formal political life began in 1921 with adoption of a constitution that designed Poland as a republic modeled after the French example, vesting most authority in the legislature. The postwar parliamentary system proved unstable and erratic. In 1922 disputes with political foes caused Pilsudski to resign his posts as chief of state and commander of the armed forces, but in 1926 he assumed power in a coup that followed four years of ineffectual government. For the next decade, Pilsudski dominated Polish affairs as strongman of a generally popular centrist regime. Military in character, the government of Pilsudski mixed democratic and dictatorial elements while pursuing sanacja, or national cleansing. After Pilsudski's death in 1935, his protégé successors drifted toward open authoritarianism.

In many respects, the Second Republic fell short of the high expectations of 1918. As happened elsewhere in Central Europe, the attempt to implant democracy did not succeed. Minority peoples became increasingly alienated, and antisemitism rose palpably in the general population. Nevertheless, interwar Poland could justifiably claim some noteworthy accomplishments: economic advances, the revival of Polish education and culture after decades of official curbs, and, above all, reaffirmation of the Polish nationhood that had been disputed so long. Despite its defects, the Second Republic retained a strong hold on later generations of Poles as a genuinely independent and authentic expression of Polish national aspirations.
