Ku dhammaystiro weedhan soo socda: Sharciga Dagaalka ee Mareykanka waxaa loola jeedaa waqtiyada taariikhda Mareykanka ee gobol, gobol, magaalo, ama Mareykanka oo dhan lagu soo rogay gacanta ciidan. Heer qaran, Madaxweynaha Mareykanka iyo Koongareeska Mareykanka labaduba waxay leeyihiin awood, xaddidaadyo gaar ah, si ay u soo saaraan sharciga dagaalka maadaama labaduba ay mas'uul ka noqon karaan maleeshiyada. Gobol kasta, guddoomiyuhu wuxuu awood u leeyahay inuu ku soo rogo sharciga dagaalka gudaha xuduudaha gobolka. Dalka Mareykanka, sharciga dagaalka waxaa loo adeegsaday xaalado kooban, sida New Orleans intii lagu jiray Dagaalkii New Orleans; ka dib masiibooyin waaweyn, sida Dabkii Weynaa ee Chicago ee 1871, dhulgariirkii San Francisco ee 1906, ama intii lagu jiray rabshadaha, sida Omaha rabshadaha jinsiyadeed ee 1919 ama rabshadaha Lexington ee 1920; hoggaamiyeyaasha maxalliga ah waxay ku dhawaaqeen sharciga dagaalka si ay uga ilaaliyaan naftooda rabshadaha dadka, sida Nauvoo, Illinois, intii lagu jiray Dagaalkii Illinois Mormon, ama Utah intii lagu jiray Dagaalkii Utah; ama ka jawaabista fowdada la xiriirta mudaaharaadyada iyo rabshadaha, sida
1934-tii weerar ka dhacay xeebta galbeed ee Hawaii ka dib weerarkii Japan ee Pearl Harbor, iyo intii lagu jiray dhaqdhaqaaqa xuquuqda madaniga ah ee ka jawaabaya rabshadihii Cambridge ee 1963.
