means "over", "surrounding": a noun is the thing people argue, compete or negotiate about. It goes straight after the noun, and the rest of the sentence says who clashed or what was debated. It is often written in kana, をめぐって, and belongs to news and formal writing.
、。

、。

、。

を巡って or について
is a plain "about" and goes with any verb of saying or thinking. を巡って needs more than one side: a dispute, a debate, rival claims, rumours going round. With one person writing or explaining, use について.
。

、。
Scholars are divided over how to interpret the history.
- × 日本の歴史を巡ってレポートを書いた → 日本の歴史についてレポートを書いた
