Editing Bethlehem, Pennsylvania (section)

===20th century===
In 1901, the Borough of Northampton Heights was incorporated. Starting in 1904, the borough of Bethlehem began a concerted effort to merge with its neighboring municipalities. In 1904 Bethlehem absorbed West Bethlehem followed shortly after in 1905 by Hottlesville. South Bethlehem would attempt to resist merger and incorporated themselves as their own city in 1913, however, the [[Supreme Court of Pennsylvania]] struck down their incorporation as unconstitutional in 1915 and in 1917 South Bethlehem would be annexed.

Following the merger with South Bethlehem, the new consolidated City of Bethlehem was incorporated. [[Bethlehem Steel]] executive [[Archibald Johnston (Bethlehem)|Archibald Johnston]] was elected the new city's first mayor. Northampton Heights was incorporated into the city in 1920 after significant local resistance and a failed proposed merger between Northampton Heights and [[Hellertown, Pennsylvania|Hellertown]] to make a rival city. With the annexation of [[Hottlesville, Pennsylvania|Hottlesville]], [[Macada, Pennsylvania|Macada]], [[Altonah, Pennsylvania|Altonah]], and the former town of [[Shimersville, Northampton County, Pennsylvania|Shimersville]], Bethlehem's present borders were established.
