Other European states

The United Kingdom, Belgium, the Netherlands, Portugal, the Russian Empire (including Poland and Finland), and the Ottoman Empire did not encounter major national or Radical revolutions in 1848. Sweden and Norway were also little affected. Serbia, though formally unaffected by the revolt as it was a part of the Ottoman state, actively supported Serbian revolutionaries in the Habsburg Empire.

In some countries, uprisings had already occurred demanding similar reforms to the Revolutions of 1848, but with little success. This was the case for the Kingdom of Poland and the Grand Duchy of Lithuania, which had seen a series of uprisings before or after but not during 1848: the November Uprising of 1830–1831; the Kraków Uprising of 1846 (notable for being quelled by the anti-revolutionary Galician slaughter), and later on the January Uprising of 1863–1865.

In other countries, the relative calm could be attributed to the fact that they had already gone through revolutions or civil wars in the preceding years, and therefore already enjoyed many of the reforms which Radicals elsewhere were demanding in 1848. This was largely the case for Belgium (the Belgian Revolution in 1830–1831); Portugal (the large Liberal Wars of 1828–1834, and the minor civil war of Patuleia in 1846–1847); and Switzerland (the Sonderbund War of 1847)

In yet other countries, the absence of unrest was partly due to governments taking action to prevent revolutionary unrest, and pre-emptively grant some of the reforms demanded by revolutionaries elsewhere. This was notably the case for the Netherlands, where King William II decided to alter the Dutch constitution to reform elections and voluntarily reduce the power of the monarchy. The same might be said of Switzerland, where a new constitutional regime was introduced in 1848: the Swiss Federal Constitution was a revolution of sorts, laying the foundation of Swiss society as it is today.

While no major political upheavals occurred in the Ottoman Empire as such, political unrest did occur in some of its vassal states. In Serbia, feudalism was abolished and the power of the Serbian prince was reduced with the Constitution of Serbia in 1838.
