title: How to use "participant" vs. "participant of" correctly?
body: <p>I trying to figure out the correct usage of "participant of" (P1344) and participant (P710).</p>
  
  <p>As sample I want the participants of the US Civil War.
  The first statement:</p>
  
  <pre><code>SELECT ?label WHERE {
    wd:Q8676 wdt:P710 ?subj.
    ?subj rdfs:label ?label.
    FILTER((LANG(?label)) = "en")
  }
  </code></pre>
  
  <p>returns the Union &amp; CSA.</p>
  
  <p>So I tried the "reverse" Statement with participant of:</p>
  
  <pre><code>SELECT ?label WHERE {
    ?subj wdt:P1344 wd:Q8676.
    ?subj rdfs:label ?label.
    FILTER((LANG(?label)) = "en")
  }
  </code></pre>
  
  <p>Which gives me a list of 9 names and the CSA, but not the Union.</p>
  
  <p>Thus, I am a bit confused, why 1) there are several people listed, especially since I don't know any of them. (My guess those are unaffiliated ones), 2) the Union is missing, 3) how does the correct statement for participant of looks like.</p>
