自1919年下半年至1920年7月,前后仅一年的时间内,北洋军阀集团内部派系斗争形势千变万化:安福系由身处窘境而发展为势力强大;皖系遽尔达于鼎盛却很快就堕入败亡的深渊;反皖同盟迅速成熟壮大,仅几个月的时间就实现了倒皖的目标.本文试就这种背景下的徐树铮西北筹边与军阀派系政争的关系作一探讨. Since the second half of 1919 to July 1920, the factional struggles within the Beiyang warlord group have been ever-changing within a year or so: An-fu was developed into a mighty force by being in a dilemma; It will fall into the abyss of defeat.Anti-Anhui alliance quickly matured and expanded, and only achieved the goal of pouring Anhui in a few months.This paper tries to discuss the relationship between the northwest-facing eddies and warlords factionalism in this background.
