2017年12月11日，上海民族黨（簡稱滬民黨）發起人何岸泉在紐約曼哈頓大街上舉牌“上海民族獨立萬歲”，並在推特發布他的舉牌照片，同時聲稱將於2018年元旦宣布籌組上海民族黨。2018年元旦，何岸泉如約在他的 Youtube 頻道上發表《滬獨啟航》演說。此時，已有趙長明、張會來和李剛等11位人士加入滬民黨，成為首批創黨黨員。何岸泉誓言募集到50位創黨黨員後，滬民黨將正式成立。
7月10日至7月18日，先後共9人被批准入黨，黨員人數達到51位，符合宣布正式成立條件。無獨有偶，紐約州也於7月18日批准了上海民族黨（SHANGHAI NATIONAL PARTY）的註冊申請。籌委會當即決定，在推特宣布上海民族黨正式成立。
On December 11, 2017, the founder of SNP, Mr. He Anquan held a sign stating “Long Live the independence of Shanghai Nation” on the street of Manhattan, New York. Later on that day, he published the photos of he holding the sign on his twitter account, and announced that he is going to formally declare the establishment of SNP on the New Year of 2018. On January 1st, 2018, as scheduled, Mr. He AnQuan published his speech titled as “The Debarkation of Shanghai Independence”. By this time, eleven people, including Changming Zhao, Huilai Zhang, Gang Li, etc., have already taken their oaths and became the founding members of SNP. Mr. He Anquan decided to declare the formal establishment of SNP as soon as there were fifty party members taking their oaths. On May, 24, 2018, when the number of party members approached 40, Mr. He Anquan, the cartoonist “Rebel Pepper” (Mr. Wang) and Mr. Shao Ma composed the Preparation Committee of Shanghai National Party. On the meeting held on June 10, 2018, the Preparation Committee decided to formally register SNP as a political party in the beginning of July 2018. On July 5, 2018, the Preparation Committee submitted their formal registration application to the state government of the New York state. Between July 10th and July 18th, nine more people were approved as party members, so the number of SNP party members hit the target 50, meeting the prerequisite of the declaration of establishment of SNP. The New York state government also approved the registration application of SNP on July 18, 2018. Based on the approval and the number of party members, the Preparation Committee decided to announce the formal establishment of SNP on their official twitter account (@ShanghaiNationP).
