  Quotes of public figures can mark turning points in history. A quote can
explain its originator's actions, foreshadowing political or personal decisions
and revealing character traits. Impactful quotes cross language barriers and
influence the general population's reaction to specific stances, always facing
the risk of being misattributed or taken out of context. The provision of a
cross-lingual knowledge graph of quotes that establishes the authenticity of
quotes and their contexts is of great importance to allow the exploration of
the lives of important people as well as topics from the perspective of what
was actually said. In this paper, we present QuoteKG, the first multilingual
knowledge graph of quotes. We propose the QuoteKG creation pipeline that
extracts quotes from Wikiquote, a free and collaboratively created collection
of quotes in many languages, and aligns different mentions of the same quote.
QuoteKG includes nearly one million quotes in $55$ languages, said by more than
$69,000$ people of public interest across a wide range of topics. QuoteKG is
publicly available and can be accessed via a SPARQL endpoint.
