Final answer:
The assertion that The Walking Purchase improved relations between the Penn family and the Delaware Indians is false. This event actually resulted in significant deceit and loss of trust, marking a departure from William Penn's earlier fair dealings and friendship with the Lenape tribe.
Step-by-step explanation:
The statement that 'The Walking Purchase resulted in warmer relations between the Penn family and the Delaware Indians' is false. While William Penn initially established peaceful relations and fair land acquisitions with the Delaware (Lenape) Indians, following his death, his sons and subsequent settlers deteriorated these relations. The Walking Purchase of 1737, engineered by Penn's sons, was a particularly egregious act of fraud that exploited the goodwill established by Penn. The sons utilized a forged deed and an unfairly mapped out 'walk' to acquire significantly more Lenape land than what would have been agreed upon. This act led to a bitter and broken relationship between the settlers and the Delaware Indians, contrary to the peaceful and respectful interactions that William Penn had established in prior decades.
