The first phase of Wikidata (the MVP so to speak) was purely as a common repository for interwiki links, not a general knowledge engine/knowledge graph. The latter is a lot more recent.
General statements were added in 2013 which is still before KE.
The query service (the SPARQL endpoint) is probably the most KE like part, and that was later, in 2015. Still before KE but much closer. I think (hard to say because nobody gave a straight answer) that KE was more going to be about federation and searching non wikimedia (Free) resources.
