\nみなさんは花火大会に参加したことがあるだろうか。日本には地元の人に親しまれるものや多くの観光客を集めるものなど様々な花火大会があり、今や日本の夏の風物詩となっている。では花火文化はどのように人々に浸透していったのだろうか。今回は花火大会の歴史と人出に注目して花火文化の広がりについて考える。\n

日本の花火文化を調べる前に、まずは花火の発祥について解説する。\n

花火の原料となる火薬の発明については諸説あるものの、一般的には紀元前中国の錬丹術（薬づくり）によって生み出されたとされており、１２世紀ごろに火器などの軍事に利用されるようになったことでヨーロッパに伝わったといわれる。\n

その後１４世紀にはイタリアで観賞用としての役割を経たものの、日本へは、はじめ火器および「のろし」として１６世紀に火縄銃とともに伝わった。\n

日本で観賞用の花火が登場するのはさらに後の江戸時代のことである。\n
