The Collins Line was the common name for the American shipping company started by Israel Collins and then built up by his son Edward Knight Collins, formally called the New York and Liverpool United States Mail Steamship Company. Under Edward Collins' guidance, the company grew to be a serious competitor on the transatlantic routes to the British Cunard shipping company.
