proletariërs aller landen, verenigt u

== Dutch == === Alternative forms === proletariërs aller landen, verenigt U === Phrase === proletariërs aller landen, verenigt u workers of the world, unite ==== Usage notes ==== The usage of u as second person plural pronoun is dated in modern Dutch, and the genitive aller landen is positively archaic, but both are retained here as part of an ossified set phrase. The modernized version would be proletariërs van alle landen, verenig je, but this rendition is vanishingly rare.
