Chivalric

"And yet, how much chivalric association has Shakespeare flung around their bloom! But for him, the wars of the "rival houses" would be but obscure chronicles of inglorious wars—fighting for fighting sake: no liberty to be defended or obtained, and no foreign enemy driven triumphantly from the frontier: but for him, "the aspiring blood of Lancaster" would long since have sunk in the ground."

"Some historical chivalric conventions remain relevant to this day, in certain circumstances. Historically, a gentleman would walk on the “outside” of the sidewalk, closest to the street, to shield his female companion from the splash of passing carriages. This is a subtle and harmless gesture of consideration that can still be practiced today."
