1935年年底,在平津形势日趋严重的情况下,中共中央在陕北瓦窑堡召开了政治局会议,分析形势,制定斗争策略;还决定派刘少奇到天津主持北方局工作。发展北方地区的民族统一战线,领导抗日斗争。
        1936年3月下旬,刘少奇由陕北来津重建北方局,并兼任书记。刘少奇和夫人,在津住在今和平区黑龙江路隆泰里19号的二楼上。刘少奇公开身份是南开大学教授“周先生” ,在家养病。室内陈设十分简陋,只有1张木床、1个方桌、1把木椅和一些生活用品。
        该地处于原日、法租界交界处,周围街道里弄,纵横错落,四通八达,既便于隐蔽,又利于转移。当时,楼下是 “惠兴德成衣铺” ,只有师徒二人,都是外乡人,只顾做生意,单纯可靠。出入人员可以假装到成衣店量体裁衣。站在二楼的窗前,可以了望到滨江道和黑龙江路上的动静,很利于秘密工作者工作、居住。
        刘少奇通过林枫,与地方党组织保持着密切的联系,在短短的一年多时间里,成功地领导了“五二八” 天津学生反日大示威; 卓有成效地推动了抗日民族统一战线的开展,把天津的抗日救亡运动推向新的高潮。
        刘少奇并在此写下了许多指导党的工作和白区斗争的著述。如以K.Y为名撰写的《肃清立三路线的残余——关门主义、冒险主义》 、《关于白区工作给中央的信》 ,以吕文署名撰写的《论合作抗敌的一封信》 、《论 “全国抗战是否立刻爆发” 和救亡阵线当前主要的任务》等等,都是党的重要文献。
        1982年,天津市人民政府,确定隆泰里19号为市级文物保护单位,并镶嵌了一块用大理石刻制的标志牌。上述“天津市市级文物保护单位——中共北方局旧址” 。
