This short paper describes the first steps in a project to construct a
knowledge graph for Brazilian history based on the Brazilian Dictionary of
Historical Biographies (DHBB) and Wikipedia/Wikidata. We contend that large
repositories of Brazilian-named entities (people, places, organizations, and
political events and movements) would be beneficial for extracting information
from Portuguese texts. We show that many of the terms/entities described in the
DHBB do not have corresponding concepts (or Q items) in Wikidata, the largest
structured database of entities associated with Wikipedia. We describe previous
work on extracting information from the DHBB and outline the steps to construct
a Wikidata-based historical knowledge graph
